Summary
In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task.

Summary
An issue was discovered in the Linux kernel through 4.17.10. There is an invalid pointer dereference in btrfs_root_node() when mounting a crafted btrfs image, because of a lack of chunk block group mapping validation in btrfs_read_block_groups in fs/btrfs/extent-tree.c, and a lack of empty-tree checks in check_leaf in fs/btrfs/tree-checker.c.

Summary
An issue was discovered in the Linux kernel through 4.17.11, as used in Xen through 4.11.x. The xen_failsafe_callback entry point in arch/x86/entry/entry_64.S does not properly maintain RBX, which allows local users to cause a denial of service (uninitialized memory usage and system crash). Within Xen, 64-bit x86 PV Linux guest OS users can trigger a guest OS crash or possibly gain privileges.

Summary
The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. These are the specifics of this vulnerability: In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs, (void *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(&ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes).

The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(\u0026ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) \u0026efs); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes)." } ], "problemTypes": [ { "descriptions": [ { "description": "n/a", "lang": "en", "type": "text" } ] } ], "providerMetadata": { "dateUpdated": "2019-04-08T19:06:07", "orgId": "8254265b-2729-46b6-b9e3-3dfca2d5bfca", "shortName": "mitre" }, "references": [ { "name": "[oss-security] 20171206 Info Leak in the Linux Kernel via Bluetooth", "tags": [ "mailing-list", "x_refsource_MLIST" ], "url": "http://seclists.org/oss-sec/2017/q4/357" }, { "name": "DSA-4082", "tags": [ "vendor-advisory", "x_refsource_DEBIAN" ], "url": "https://www.debian.org/security/2018/dsa-4082" }, { "name": "RHSA-2018:1062", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ], "url": "https://access.redhat.com/errata/RHSA-2018:1062" }, { "name": "RHSA-2018:0654", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ], "url": "https://access.redhat.com/errata/RHSA-2018:0654" }, { "name": "RHSA-2018:1319", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ], "url": "https://access.redhat.com/errata/RHSA-2018:1319" }, { "tags": [ "x_refsource_CONFIRM" ], "url": "https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6.0" }, { "name": "RHSA-2018:0676", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ], "url": "https://access.redhat.com/errata/RHSA-2018:0676" }, { "name": "RHSA-2018:1170", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ], "url": "https://access.redhat.com/errata/RHSA-2018:1170" }, { "name": "RHSA-2018:1130", "tags": [ "vendor-advisory", "x_refsource_REDHAT" ], "url": "https://access.redhat.com/errata/RHSA-2018:1130" }, { "name": "DSA-4073", "tags": [ "vendor-advisory", "x_refsource_DEBIAN" ], "url": "https://www.debian.org/security/2017/dsa-4073" }, { "name": "102101", "tags": [ "vdb-entry", "x_refsource_BID" ], "url": "http://www.securityfocus.com/bid/102101" }, { "name": "USN-3933-2", "tags": [ "vendor-advisory", "x_refsource_UBUNTU" ], "url": "https://usn.ubuntu.com/3933-2/" }, { "name": "USN-3933-1", "tags": [ "vendor-advisory", "x_refsource_UBUNTU" ], "url": "https://usn.ubuntu.com/3933-1/" } ], "x_legacyV4Record": { "CVE_data_meta": { "ASSIGNER": "cve@mitre.org", "DATE_ASSIGNED": "2017-12-05", "ID": "CVE-2017-1000410", "REQUESTER": "ben@armis.com", "STATE": "PUBLIC" }, "affects": { "vendor": { "vendor_data": [ { "product": { "product_data": [ { "product_name": "n/a", "version": { "version_data": [ { "version_value": "n/a" } ] } } ] }, "vendor_name": "n/a" } ] } }, "data_format": "MITRE", "data_type": "CVE", "data_version": "4.0", "description": { "description_data": [ { "lang": "eng", "value": "The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages.

Summary
In the Linux kernel before 4.20.12, net/ipv4/netfilter/nf_nat_snmp_basic_main.c in the SNMP NAT module has insufficient ASN.1 length checks (aka an array index error), making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmp_version and snmp_helper.

Summary
A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.

Summary
arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes.

This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "name": "USN-3821-1", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3821-1/" }, { "name": "https://github.com/torvalds/linux/commit/2a3f93459d689d990b3ecfbe782fec89b97d3279", "refsource": "MISC", "url": "https://github.com/torvalds/linux/commit/2a3f93459d689d990b3ecfbe782fec89b97d3279" }, { "name": "https://www.openwall.com/lists/oss-security/2018/10/02/2", "refsource": "MISC", "url": "https://www.openwall.com/lists/oss-security/2018/10/02/2" }, { "name": "https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.18.12", "refsource": "MISC", "url": "https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.18.12" }, { "name": "RHSA-2018:3656", "refsource": "REDHAT", "url": "https://access.redhat.com/errata/RHSA-2018:3656" }, { "name": "https://github.com/torvalds/linux/commit/d26c25a9d19b5976b319af528886f89cf455692d", "refsource": "MISC", "url": "https://github.com/torvalds/linux/commit/d26c25a9d19b5976b319af528886f89cf455692d" }, { "name": "105550", "refsource": "BID", "url": "http://www.securityfocus.com/bid/105550" }, { "name": "USN-3821-2", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3821-2/" }, { "name": "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2a3f93459d689d990b3ecfbe782fec89b97d3279", "refsource": "MISC", "url": "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2a3f93459d689d990b3ecfbe782fec89b97d3279" }, { "name": "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d26c25a9d19b5976b319af528886f89cf455692d", "refsource": "MISC", "url": "http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d26c25a9d19b5976b319af528886f89cf455692d" }, { "name": "DSA-4313", "refsource": "DEBIAN", "url": "https://www.debian.org/security/2018/dsa-4313" }, { "name": "USN-3931-1", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3931-1/" }, { "name": "USN-3931-2", "refsource": "UBUNTU", "url": "https://usn.ubuntu.com/3931-2/" } ] } } } }, "cveMetadata": { "assignerOrgId": "8254265b-2729-46b6-b9e3-3dfca2d5bfca", "assignerShortName": "mitre", "cveId": "CVE-2018-18021", "datePublished": "2018-10-07T06:00:00", "dateReserved": "2018-10-07T00:00:00", "dateUpdated": "2024-08-05T11:01:14.808Z", "state": "PUBLISHED" }, "dataType": "CVE_RECORD", "dataVersion": "5.1" }

Summary
An issue was discovered in can_can_gw_rcv in net/can/gw.c in the Linux kernel through 4.19.13. The CAN frame modification rules allow bitwise logical operations that can be also applied to the can_dlc field. The privileged user "root" with CAP_NET_ADMIN can create a CAN frame modification rule that makes the data length code a higher value than the available CAN frame data size. In combination with a configured checksum calculation where the result is stored relatively to the end of the data (e.g. cgw_csum_xor_rel) the tail of the skb (e.g. frag_list pointer in skb_shared_info) can be rewritten which finally can cause a system crash. Because of a missing check, the CAN drivers may write arbitrary content beyond the data registers in the CAN controller's I/O memory when processing can-gw manipulated outgoing frames.
