Exploitability:
CWE CWE-200
CAPEC
  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.
  • Reusing Session IDs (aka Session Replay)
    This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.
  • Using Slashes in Alternate Encoding
    This attack targets the encoding of the Slash characters. An attacker would try to exploit common filtering problems related to the use of the slashes characters to gain access to resources on the target host. Directory-driven systems, such as file systems and databases, typically use the slash character to indicate traversal between directories or other container components. For murky historical reasons, PCs (and, as a result, Microsoft OSs) choose to use a backslash, whereas the UNIX world typically makes use of the forward slash. The schizophrenic result is that many MS-based systems are required to understand both forms of the slash. This gives the attacker many opportunities to discover and abuse a number of common filtering problems. The goal of this pattern is to discover server software that only applies filters to one version, but not the other.

    NASL id SUSE_11_KERNEL-140709.NASL
    description The SUSE Linux Enterprise 11 Service Pack 3 kernel has been updated to fix various bugs and security issues. The following security bugs have been fixed : - The rds_ib_xmit function in net/rds/ib_send.c in the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel 3.7.4 and earlier allows local users to cause a denial of service (BUG_ON and kernel panic) by establishing an RDS connection with the source IP address equal to the IPoIB interfaces own IP address, as demonstrated by rds-ping. (bnc#767610). (CVE-2012-2372) - The Linux kernel before 3.12.2 does not properly use the get_dumpable function, which allows local users to bypass intended ptrace restrictions or obtain sensitive information from IA64 scratch registers via a crafted application, related to kernel/ptrace.c and arch/ia64/include/asm/processor.h. (bnc#847652). (CVE-2013-2929) - Interpretation conflict in drivers/md/dm-snap-persistent.c in the Linux kernel through 3.11.6 allows remote authenticated users to obtain sensitive information or modify data via a crafted mapping to a snapshot block device. (bnc#846404). (CVE-2013-4299) - The ath9k_htc_set_bssid_mask function in drivers/net/wireless/ath/ath9k/htc_drv_main.c in the Linux kernel through 3.12 uses a BSSID masking approach to determine the set of MAC addresses on which a Wi-Fi device is listening, which allows remote attackers to discover the original MAC address after spoofing by sending a series of packets to MAC addresses with certain bit manipulations. (bnc#851426). (CVE-2013-4579) - Multiple buffer underflows in the XFS implementation in the Linux kernel through 3.12.1 allow local users to cause a denial of service (memory corruption) or possibly have unspecified other impact by leveraging the CAP_SYS_ADMIN capability for a (1) XFS_IOC_ATTRLIST_BY_HANDLE or (2) XFS_IOC_ATTRLIST_BY_HANDLE_32 ioctl call with a crafted length value, related to the xfs_attrlist_by_handle function in fs/xfs/xfs_ioctl.c and the xfs_compat_attrlist_by_handle function in fs/xfs/xfs_ioctl32.c.

(bnc#870173). (CVE-2014-0055) - drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions. (bnc#870576). (CVE-2014-0077) - The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk. (bnc#866102). (CVE-2014-0101) - Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel through 3.13.6 allows attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation. (bnc#867723). (CVE-2014-0131) - The ioapic_deliver function in virt/kvm/ioapic.c in the Linux kernel through 3.14.1 does not properly validate the kvm_irq_delivery_to_apic return value, which allows guest OS users to cause a denial of service (host OS crash) via a crafted entry in the redirection table of an I/O APIC. NOTE: the affected code was moved to the ioapic_service function before the vulnerability was announced. (bnc#872540). (CVE-2014-0155) - The fst_get_iface function in drivers/net/wan/farsync.c in the Linux kernel before 3.11.7 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCWANDEV ioctl call. (bnc#858869). (CVE-2014-1444) - The wanxl_ioctl function in drivers/net/wan/wanxl.c in the Linux kernel before 3.11.7 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from kernel memory via an ioctl call. (bnc#858870). (CVE-2014-1445) - The yam_ioctl function in drivers/net/hamradio/yam.c in the Linux kernel before 3.12.8 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG ioctl call. (bnc#858872). (CVE-2014-1446) - The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context. (bnc#863335). (CVE-2014-1874) - The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets. (bnc#867531). (CVE-2014-2309) - net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function. (bnc#868653). (CVE-2014-2523) - The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports.

(bnc#873374). (CVE-2014-2851) - The try_to_unmap_cluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service (system crash) by triggering a memory-usage pattern that requires removal of page-table mappings. (bnc#876102). (CVE-2014-3122) - The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced. (bnc#877257). (CVE-2014-3144) - The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced. (bnc#877257). (CVE-2014-3145) - kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number.

(bnc#883795). (CVE-2014-4652) - sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure possession of a read/write lock, which allows local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access. (bnc#883795). (CVE-2014-4653) - The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call. (bnc#883795). (CVE-2014-4654) - The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. (bnc#883795). (CVE-2014-4655) - Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function. (bnc#883795). (CVE-2014-4656) - The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls. (bnc#885725).

Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's futex subsystem handled reference counting when requeuing futexes during futex_wait(). A local, unprivileged user could use this flaw to zero out the reference counter of an inode or an mm struct that backs up the memory area of the futex, which could lead to a use-after-free flaw, resulting in a system crash or, potentially, privilege escalation. (CVE-2014-0205, Important) * A NULL pointer dereference flaw was found in the way the Linux kernel's networking implementation handled logging while processing certain invalid packets coming in via a VxLAN interface.

(bnc#806431) - CVE-2013-4162: The udp_v6_push_pending_frames function in net/ipv6/udp.c in the IPv6 implementation in the Linux kernel through 3.10.3 makes an incorrect function call for pending data, which allows local users to cause a denial of service (BUG and system crash) via a crafted application that uses the UDP_CORK option in a setsockopt system call. (bnc#831058) - CVE-2014-0203: The __do_follow_link function in fs/namei.c in the Linux kernel before 2.6.33 does not properly handle the last pathname component during use of certain filesystems, which allows local users to cause a denial of service (incorrect free operations and system crash) via an open system call. (bnc#883526) - CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced. (bnc#877257) - CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced. (bnc#877257) - CVE-2014-3917: kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number. (bnc#880484) - CVE-2014-4508: arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000. (bnc#883724) - CVE-2014-4652: Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access. (bnc#883795) - CVE-2014-4653: sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure possession of a read/write lock, which allows local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access. (bnc#883795) - CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call. (bnc#883795) - CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. (bnc#883795) - CVE-2014-4656: Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function. (bnc#883795) - CVE-2014-4667: The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet. (bnc#885422) - CVE-2014-4699: The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls. (bnc#885725) - CVE-2014-4943: The PPPoL2TP feature in net/l2tp/l2tp_ppp.c in the Linux kernel through 3.15.6 allows local users to gain privileges by leveraging data-structure differences between an l2tp socket and an inet socket. (bnc#887082) - CVE-2014-5077: The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction. (bnc#889173) - CVE-2013-7266: The mISDN_sock_recvmsg function in drivers/isdn/mISDN/socket.c in the Linux kernel before 3.12.4 does not ensure that a certain length value is consistent with the size of an associated data structure, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call. (bnc#854722) - CVE-2013-7267: The atalk_recvmsg function in net/appletalk/ddp.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call. (bnc#854722) - CVE-2013-7268: The ipx_recvmsg function in net/ipx/af_ipx.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call. (bnc#854722) - CVE-2013-7269: The nr_recvmsg function in net/netrom/af_netrom.c in the Linux kernel before 3.12.4 updates a certain length value without ensuring that an associated data structure has been initialized, which allows local users to obtain sensitive information from kernel memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call.

  • NASL family Mandriva Local Security Checks
    NASL id MANDRIVA_MDVSA-2014-124.NASL
    description Multiple vulnerabilities has been found and corrected in the Linux kernel : kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number (CVE-2014-3917). The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification (CVE-2014-3153). Race condition in the ath_tx_aggr_sleep function in drivers/net/wireless/ath/ath9k/xmit.c in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via a large amount of network traffic that triggers certain list deletions (CVE-2014-2672). The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 do not check whether a certain length value is sufficiently large, which allows local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr and __skb_get_nlattr_nest functions before the vulnerability was announced (CVE-2014-3144). The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel through 3.14.3 uses the reverse order in a certain subtraction, which allows local users to cause a denial of service (over-read and system crash) via crafted BPF instructions. NOTE: the affected code was moved to the __skb_get_nlattr_nest function before the vulnerability was announced (CVE-2014-3145). Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the Linux kernel through 3.14.1 allows local users to cause a denial of service (use-after-free and system crash) or possibly gain privileges via a crafted application that leverages an improperly managed reference counter (CVE-2014-2851). The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the LECHO !OPOST case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings (CVE-2014-0196). The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device (CVE-2014-1738). The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device (CVE-2014-1737). The rds_iw_laddr_check function in net/rds/iw.c in the Linux kernel through 3.14 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports (CVE-2014-2678). drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions (CVE-2014-0077). The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets (CVE-2014-2309). Multiple array index errors in drivers/hid/hid-multitouch.c in the Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_HID_MULTITOUCH is enabled, allow physically proximate attackers to cause a denial of service (heap memory corruption, or NULL pointer dereference and OOPS) via a crafted device (CVE-2013-2897). net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function (CVE-2014-2523). Race condition in the mac80211 subsystem in the Linux kernel before 3.13.7 allows remote attackers to cause a denial of service (system crash) via network traffic that improperly interacts with the WLAN_STA_PS_STA state (aka power-save mode), related to sta_info.c and tx.c (CVE-2014-2706). The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk (CVE-2014-0101). The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes, which allows local users to obtain sensitive information from kernel memory, cause a denial of service (memory corruption and system crash), or possibly gain privileges via a writev system call with a crafted pointer (CVE-2014-0069). arch/s390/kernel/head64.S in the Linux kernel before 3.13.5 on the s390 platform does not properly handle attempted use of the linkage stack, which allows local users to cause a denial of service (system crash) by executing a crafted instruction (CVE-2014-2039). Buffer overflow in virt/kvm/irq_comm.c in the KVM subsystem in the Linux kernel before 3.2.24 allows local users to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to Message Signaled Interrupts (MSI), irq routing entries, and an incorrect check by the setup_routing_entry function before invoking the kvm_set_irq function (CVE-2012-2137). The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context (CVE-2014-1874). The updated packages provides a solution for these security issues.

    NASL id SL_20140903_KERNEL_ON_SL5_X.NASL
    description - An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. (CVE-2014-3917, Moderate) This update also fixes the following bugs : - A bug in the journaling code (jbd and jbd2) could, under very heavy workload of fsync() operations, trigger a BUG_ON and result in a kernel oops. Also, fdatasync() could fail to immediately write out changes in the file size only. These problems have been resolved by backporting a series of patches that fixed these problems in the respective code on Scientific Linux 6. This update also improves performance of ext3 and ext4 file systems. - Due to a bug in the ext4 code, the fdatasync() system call did not force the inode size change to be written to the disk if it was the only metadata change in the file. This could result in the wrong inode size and possible data loss if the system terminated unexpectedly. The code handling inode updates has been fixed and fdatasync() now writes data to the disk as expected in this situation. - A workaround to a DMA read problem in the tg3 driver was incorrectly applied to the whole Broadcom 5719 and 5720 chipset family. This workaround is valid only to the A0 revision of the 5719 chips and for other revisions and chips causes occasional Tx timeouts. This update correctly applies the aforementioned workaround only to the A0 revision of the 5719 chips. - Due to a bug in the page writeback code, the system could become unresponsive when being under memory pressure and heavy NFS load. This update fixes the code responsible for handling of dirty pages, and dirty page write outs no longer flood the work queue. The system must be rebooted for this update to take effect.

(CVE-2014-3917, Moderate) This update also fixes the following bugs : * A bug in the journaling code (jbd and jbd2) could, under very heavy workload of fsync() operations, trigger a BUG_ON and result in a kernel oops. Also, fdatasync() could fail to immediately write out changes in the file size only. These problems have been resolved by backporting a series of patches that fixed these problems in the respective code on Red Hat Enterprise Linux 6. This update also improves performance of ext3 and ext4 file systems. (BZ#1116027) * Due to a bug in the ext4 code, the fdatasync() system call did not force the inode size change to be written to the disk if it was the only metadata change in the file. This could result in the wrong inode size and possible data loss if the system terminated unexpectedly. The code handling inode updates has been fixed and fdatasync() now writes data to the disk as expected in this situation. (BZ#1117665) * A workaround to a DMA read problem in the tg3 driver was incorrectly applied to the whole Broadcom 5719 and 5720 chipset family. This workaround is valid only to the A0 revision of the 5719 chips and for other revisions and chips causes occasional Tx timeouts. This update correctly applies the aforementioned workaround only to the A0 revision of the 5719 chips. (BZ#1121017) * Due to a bug in the page writeback code, the system could become unresponsive when being under memory pressure and heavy NFS load. This update fixes the code responsible for handling of dirty pages, and dirty page write outs no longer flood the work queue. (BZ#1125246) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. (CVE-2014-3917, Moderate) This update also fixes the following bugs : * A bug in the mtip32xx driver could prevent the Micron P420m PCIe SSD devices with unaligned I/O access from completing the submitted I/O requests. This resulted in a livelock situation and rendered the Micron P420m PCIe SSD devices unusable. To fix this problem, mtip32xx now checks whether an I/O access is unaligned and if so, it uses the correct semaphore. (BZ#1125776) * A series of patches has been backported to improve the functionality of a touch pad on the latest Lenovo laptops in Red Hat Enterprise Linux 7. (BZ#1122559) * Due to a bug in the bnx2x driver, a network adapter could be unable to recover from EEH error injection. The network adapter had to be taken offline and rebooted in order to function properly again. With this update, the bnx2x driver has been corrected and network adapters now recover from EEH errors as expected. (BZ#1107722) * Previously, if an hrtimer interrupt was delayed, all future pending hrtimer events that were queued on the same processor were also delayed until the initial hrtimer event was handled. This could cause all hrtimer processing to stop for a significant period of time. To prevent this problem, the kernel has been modified to handle all expired hrtimer events when handling the initially delayed hrtimer event. (BZ#1113175) * A previous change to the nouveau driver introduced a bit shift error, which resulted in a wrong display resolution being set with some models of NVIDIA controllers. With this update, the erroneous code has been corrected, and the affected NVIDIA controllers can now set the correct display resolution. (BZ#1114869) * Due to a NULL pointer dereference bug in the be2net driver, the system could experience a kernel oops and reboot when disabling a network adapter after a permanent failure. This problem has been fixed by introducing a flag to keep track of the setup state. The failing adapter can now be disabled successfully without a kernel crash. (BZ#1122558) * Previously, the Huge Translation Lookaside Buffer (HugeTLB) allowed access to huge pages access by default. However, huge pages may be unsupported in some environments, such as a KVM guest on a PowerPC architecture, and an attempt to access a huge page in memory would result in a kernel oops. This update ensures that HugeTLB denies access to huge pages if the huge pages are not supported on the system. (BZ#1122115) * If an NVMe device becomes ready but fails to create I/O queues, the nvme driver creates a character device handle to manage such a device. Previously, a character device could be created before a device reference counter was initialized, which resulted in a kernel oops. This problem has been fixed by calling the relevant initialization function earlier in the code. (BZ#1119720) * On some firmware versions of the BladeEngine 3 (BE3) controller, interrupts remain disabled after a hardware reset. This was a problem for all Emulex-based network adapters using such a BE3 controller because these adapters would fail to recover from an EEH error if it occurred. To resolve this problem, the be2net driver has been modified to enable the interrupts in the eeh_resume handler explicitly. (BZ#1121712) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

    description Updated kernel-rt packages that fix multiple security issues are now available for Red Hat Enterprise MRG 2.5. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. (CVE-2014-3153, Important) * It was found that the Linux kernel's ptrace subsystem allowed a traced process' instruction pointer to be set to a non-canonical memory address without forcing the non-sysret code path when returning to user space. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. Note that this issue only affected systems using an Intel CPU. (CVE-2014-4699, Important) * It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. (CVE-2014-0181, Moderate) * It was found that the aio_read_events_ring() function of the Linux kernel's Asynchronous I/O (AIO) subsystem did not properly sanitize the AIO ring head received from user space. A local, unprivileged user could use this flaw to disclose random parts of the (physical) memory belonging to the kernel and/or other processes. (CVE-2014-0206, Moderate) * An out-of-bounds memory access flaw was found in the Netlink Attribute extension of the Berkeley Packet Filter (BPF) interpreter functionality in the Linux kernel's networking implementation. A local, unprivileged user could use this flaw to crash the system or leak kernel memory to user space via a specially crafted socket filter. (CVE-2014-3144, CVE-2014-3145, Moderate) * An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. (CVE-2014-3917, Moderate) * A flaw was found in the way Linux kernel's Transparent Huge Pages (THP) implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. (CVE-2014-3940, Moderate) * An integer underflow flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation processed certain COOKIE_ECHO packets. By sending a specially crafted SCTP packet, a remote attacker could use this flaw to prevent legitimate connections to a particular SCTP server socket to be made. (CVE-2014-4667, Moderate) * An information leak flaw was found in the RAM Disks Memory Copy (rd_mcp) back-end driver of the iSCSI Target subsystem of the Linux kernel. A privileged user could use this flaw to leak the contents of kernel memory to an iSCSI initiator remote client. (CVE-2014-4027, Low) Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.43 and correct these issues. The system must be rebooted for this update to take effect.

CVE-2014-3917: kernel/auditsc.c in the Linux kernel, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allowed local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number. CVE-2014-0131: Use-after-free vulnerability in the skb_segment function in net/core/skbuff.c in the Linux kernel allowed attackers to obtain sensitive information from kernel memory by leveraging the absence of a certain orphaning operation. CVE-2014-3144: The (1) BPF_S_ANC_NLATTR and (2) BPF_S_ANC_NLATTR_NEST extension implementations in the sk_run_filter function in net/core/filter.c in the Linux kernel did not check whether a certain length value is sufficiently large, which allowed local users to cause a denial of service (integer underflow and system crash) via crafted BPF instructions. CVE-2014-3145: The BPF_S_ANC_NLATTR_NEST extension implementation in the sk_run_filter function in net/core/filter.c in the Linux kernel used the reverse order in a certain subtraction, which allowed local users to cause a denial of service (over-read and system crash) via crafted BPF instructions.

    title openSUSE Security Update : kernel (openSUSE-SU-2014:0985-1)
  • NASL family Oracle Linux Local Security Checks
    NASL id ORACLELINUX_ELSA-2014-1281.NASL
    description From Red Hat Security Advisory 2014:1281 : Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. (CVE-2014-3917, Moderate) This update also fixes the following bugs : * A bug in the mtip32xx driver could prevent the Micron P420m PCIe SSD devices with unaligned I/O access from completing the submitted I/O requests. This resulted in a livelock situation and rendered the Micron P420m PCIe SSD devices unusable. To fix this problem, mtip32xx now checks whether an I/O access is unaligned and if so, it uses the correct semaphore. (BZ#1125776) * A series of patches has been backported to improve the functionality of a touch pad on the latest Lenovo laptops in Red Hat Enterprise Linux 7. (BZ#1122559) * Due to a bug in the bnx2x driver, a network adapter could be unable to recover from EEH error injection. The network adapter had to be taken offline and rebooted in order to function properly again. With this update, the bnx2x driver has been corrected and network adapters now recover from EEH errors as expected. (BZ#1107722) * Previously, if an hrtimer interrupt was delayed, all future pending hrtimer events that were queued on the same processor were also delayed until the initial hrtimer event was handled. This could cause all hrtimer processing to stop for a significant period of time. To prevent this problem, the kernel has been modified to handle all expired hrtimer events when handling the initially delayed hrtimer event. (BZ#1113175) * A previous change to the nouveau driver introduced a bit shift error, which resulted in a wrong display resolution being set with some models of NVIDIA controllers. With this update, the erroneous code has been corrected, and the affected NVIDIA controllers can now set the correct display resolution. (BZ#1114869) * Due to a NULL pointer dereference bug in the be2net driver, the system could experience a kernel oops and reboot when disabling a network adapter after a permanent failure. This problem has been fixed by introducing a flag to keep track of the setup state. The failing adapter can now be disabled successfully without a kernel crash. (BZ#1122558) * Previously, the Huge Translation Lookaside Buffer (HugeTLB) allowed access to huge pages access by default. However, huge pages may be unsupported in some environments, such as a KVM guest on a PowerPC architecture, and an attempt to access a huge page in memory would result in a kernel oops. This update ensures that HugeTLB denies access to huge pages if the huge pages are not supported on the system. (BZ#1122115) * If an NVMe device becomes ready but fails to create I/O queues, the nvme driver creates a character device handle to manage such a device. Previously, a character device could be created before a device reference counter was initialized, which resulted in a kernel oops. This problem has been fixed by calling the relevant initialization function earlier in the code. (BZ#1119720) * On some firmware versions of the BladeEngine 3 (BE3) controller, interrupts remain disabled after a hardware reset. This was a problem for all Emulex-based network adapters using such a BE3 controller because these adapters would fail to recover from an EEH error if it occurred. To resolve this problem, the be2net driver has been modified to enable the interrupts in the eeh_resume handler explicitly. (BZ#1121712) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

CVE-2014-5471: Stack consumption vulnerability in the parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel allowed local users to cause a denial of service (uncontrolled recursion, and system crash or reboot) via a crafted iso9660 image with a CL entry referring to a directory entry that has a CL entry (bnc#892490). CVE-2014-5472: The parse_rock_ridge_inode_internal function in fs/isofs/rock.c in the Linux kernel allowed local users to cause a denial of service (unkillable mount process) via a crafted iso9660 image with a self-referential CL entry (bnc#892490). CVE-2014-3917: kernel/auditsc.c in the Linux kernel, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allowed local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number (bnc#880484). CVE-2014-4652: Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel allowed local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (bnc#883795). CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel did not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allowed local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call (bnc#883795). CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel did not properly maintain the user_ctl_count value, which allowed local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls (bnc#883795). CVE-2014-4653: sound/core/control.c in the ALSA control implementation in the Linux kernel did not ensure possession of a read/write lock, which allowed local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access (bnc#883795). CVE-2014-4656: Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel allowed local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function (bnc#883795).

    description Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 5. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. (CVE-2014-3917, Moderate) This update also fixes the following bugs : * A bug in the journaling code (jbd and jbd2) could, under very heavy workload of fsync() operations, trigger a BUG_ON and result in a kernel oops. Also, fdatasync() could fail to immediately write out changes in the file size only. These problems have been resolved by backporting a series of patches that fixed these problems in the respective code on Red Hat Enterprise Linux 6. This update also improves performance of ext3 and ext4 file systems. (BZ#1116027) * Due to a bug in the ext4 code, the fdatasync() system call did not force the inode size change to be written to the disk if it was the only metadata change in the file. This could result in the wrong inode size and possible data loss if the system terminated unexpectedly. The code handling inode updates has been fixed and fdatasync() now writes data to the disk as expected in this situation. (BZ#1117665) * A workaround to a DMA read problem in the tg3 driver was incorrectly applied to the whole Broadcom 5719 and 5720 chipset family. This workaround is valid only to the A0 revision of the 5719 chips and for other revisions and chips causes occasional Tx timeouts. This update correctly applies the aforementioned workaround only to the A0 revision of the 5719 chips. (BZ#1121017) * Due to a bug in the page writeback code, the system could become unresponsive when being under memory pressure and heavy NFS load. This update fixes the code responsible for handling of dirty pages, and dirty page write outs no longer flood the work queue. (BZ#1125246) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

(bnc#883724) - CVE-2014-4652: Race condition in the tlv handler functionality in the snd_ctl_elem_user_tlv function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allows local users to obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access. (bnc#883795) - CVE-2014-4653: sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not ensure possession of a read/write lock, which allows local users to cause a denial of service (use-after-free) and obtain sensitive information from kernel memory by leveraging /dev/snd/controlCX access. (bnc#883795) - CVE-2014-4654: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not check authorization for SNDRV_CTL_IOCTL_ELEM_REPLACE commands, which allows local users to remove kernel controls and cause a denial of service (use-after-free and system crash) by leveraging /dev/snd/controlCX access for an ioctl call. (bnc#883795) - CVE-2014-4655: The snd_ctl_elem_add function in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 does not properly maintain the user_ctl_count value, which allows local users to cause a denial of service (integer overflow and limit bypass) by leveraging /dev/snd/controlCX access for a large number of SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl calls. (bnc#883795) - CVE-2014-4656: Multiple integer overflows in sound/core/control.c in the ALSA control implementation in the Linux kernel before 3.15.2 allow local users to cause a denial of service by leveraging /dev/snd/controlCX access, related to (1) index values in the snd_ctl_add function and (2) numid values in the snd_ctl_remove_numid_conflict function. (bnc#883795) - CVE-2014-4667: The sctp_association_free function in net/sctp/associola.c in the Linux kernel before 3.15.2 does not properly manage a certain backlog value, which allows remote attackers to cause a denial of service (socket outage) via a crafted SCTP packet. (bnc#885422) - CVE-2014-4699: The Linux kernel before 3.15.4 on Intel processors does not properly restrict use of a non-canonical value for the saved RIP address in the case of a system call that does not use IRET, which allows local users to leverage a race condition and gain privileges, or cause a denial of service (double fault), via a crafted application that makes ptrace and fork system calls. (bnc#885725) - CVE-2014-5077: The sctp_assoc_update function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by starting to establish an association between two endpoints immediately after an exchange of INIT and INIT ACK chunks to establish an earlier association between these endpoints in the opposite direction. (bnc#889173) - CVE-2013-4299: Interpretation conflict in drivers/md/dm-snap-persistent.c in the Linux kernel through 3.11.6 allows remote authenticated users to obtain sensitive information or modify data via a crafted mapping to a snapshot block device.

  • NASL family Red Hat Local Security Checks
    NASL id REDHAT-RHSA-2014-1281.NASL
    description Updated kernel packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system. * An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. (CVE-2014-3917, Moderate) This update also fixes the following bugs : * A bug in the mtip32xx driver could prevent the Micron P420m PCIe SSD devices with unaligned I/O access from completing the submitted I/O requests. This resulted in a livelock situation and rendered the Micron P420m PCIe SSD devices unusable. To fix this problem, mtip32xx now checks whether an I/O access is unaligned and if so, it uses the correct semaphore. (BZ#1125776) * A series of patches has been backported to improve the functionality of a touch pad on the latest Lenovo laptops in Red Hat Enterprise Linux 7. (BZ#1122559) * Due to a bug in the bnx2x driver, a network adapter could be unable to recover from EEH error injection. The network adapter had to be taken offline and rebooted in order to function properly again. With this update, the bnx2x driver has been corrected and network adapters now recover from EEH errors as expected. (BZ#1107722) * Previously, if an hrtimer interrupt was delayed, all future pending hrtimer events that were queued on the same processor were also delayed until the initial hrtimer event was handled. This could cause all hrtimer processing to stop for a significant period of time. To prevent this problem, the kernel has been modified to handle all expired hrtimer events when handling the initially delayed hrtimer event. (BZ#1113175) * A previous change to the nouveau driver introduced a bit shift error, which resulted in a wrong display resolution being set with some models of NVIDIA controllers. With this update, the erroneous code has been corrected, and the affected NVIDIA controllers can now set the correct display resolution. (BZ#1114869) * Due to a NULL pointer dereference bug in the be2net driver, the system could experience a kernel oops and reboot when disabling a network adapter after a permanent failure. This problem has been fixed by introducing a flag to keep track of the setup state. The failing adapter can now be disabled successfully without a kernel crash. (BZ#1122558) * Previously, the Huge Translation Lookaside Buffer (HugeTLB) allowed access to huge pages access by default. However, huge pages may be unsupported in some environments, such as a KVM guest on a PowerPC architecture, and an attempt to access a huge page in memory would result in a kernel oops. This update ensures that HugeTLB denies access to huge pages if the huge pages are not supported on the system. (BZ#1122115) * If an NVMe device becomes ready but fails to create I/O queues, the nvme driver creates a character device handle to manage such a device. Previously, a character device could be created before a device reference counter was initialized, which resulted in a kernel oops. This problem has been fixed by calling the relevant initialization function earlier in the code. (BZ#1119720) * On some firmware versions of the BladeEngine 3 (BE3) controller, interrupts remain disabled after a hardware reset. This was a problem for all Emulex-based network adapters using such a BE3 controller because these adapters would fail to recover from an EEH error if it occurred. To resolve this problem, the be2net driver has been modified to enable the interrupts in the eeh_resume handler explicitly. (BZ#1121712) All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
