Summary
Red Hat Security Advisory: kernel security, bug fix, and enhancement update
Severity
Important
Notes
Topic: An update for kernel is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * It was found that the Linux kernel's IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841, Important) * Several Moderate and Low impact security issues were found in the Linux kernel. Space precludes documenting each of these issues in this advisory. Refer to the CVE links in the References section for a description of each of these vulnerabilities. (CVE-2013-4312, CVE-2015-8374, CVE-2015-8543, CVE-2015-8812, CVE-2015-8844, CVE-2015-8845, CVE-2016-2053, CVE-2016-2069, CVE-2016-2847, CVE-2016-3156, CVE-2016-4581, CVE-2016-4794, CVE-2016-5412, CVE-2016-5828, CVE-2016-5829, CVE-2016-6136, CVE-2016-6198, CVE-2016-6327, CVE-2016-6480, CVE-2015-8746, CVE-2015-8956, CVE-2016-2117, CVE-2016-2384, CVE-2016-3070, CVE-2016-3699, CVE-2016-4569, CVE-2016-4578) Red Hat would like to thank Philip Pettersson (Samsung) for reporting CVE-2016-2053; Tetsuo Handa for reporting CVE-2016-2847; the Virtuozzo kernel team and Solar Designer (Openwall) for reporting CVE-2016-3156; Justin Yackoski (Cryptonite) for reporting CVE-2016-2117; and Linn Crosetto (HP) for reporting CVE-2016-3699. The CVE-2015-8812 issue was discovered by Venkatesh Pottem (Red Hat Engineering); the CVE-2015-8844 and CVE-2015-8845 issues were discovered by Miroslav Vadkerti (Red Hat Engineering); the CVE-2016-4581 issue was discovered by Eric W. Biederman (Red Hat); the CVE-2016-6198 issue was discovered by CAI Qian (Red Hat); and the CVE-2016-3070 issue was discovered by Jan Stancek (Red Hat).

It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system.

An information-leak vulnerability was found in the kernel when it truncated a file to a smaller size which consisted of an inline extent that was compressed. The data between the new file size and the old file size was not discarded and the number of bytes used by the inode were not correctly decremented, which gave the wrong report for callers of the stat(2) syscall. This wasted metadata space and allowed for the truncated data to be leaked, and data corruption or loss to occur. A caller of the clone ioctl could exploit this flaw by using only standard file-system operations without root access to read the truncated data.

A use-after-free flaw was found in the CXGB3 kernel driver when the network was considered to be congested. The kernel incorrectly misinterpreted the congestion as an error condition and incorrectly freed or cleaned up the socket buffer (skb). When the device then sent the skb's queued data, these structures were referenced. A local attacker could use this flaw to panic the system (denial of service) or, with a local account, escalate their privileges.

A flaw was discovered in the way the Linux kernel dealt with paging structures. When the kernel invalidated a paging structure that was not in use locally, it could, in principle, race against another CPU that is switching to a process that uses the paging structure in question. A local user could use a thread running with a stale cached virtual->physical translation to potentially escalate their privileges if the translation in question were writable and the physical page got reused for something critical (for example, a page table).
