Red Hat Product Security has rated this update as having Important 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-rt packages contain the Linux kernel, the core of any Linux operating system.
* A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AEC-GCM mode IPSec security association. (CVE-2015-3331, Important)
This update provides a build of the kernel-rt package for Red Hat Enterprise MRG 2.5, which is layered on Red Hat Enterprise Linux 6.
The kernel-rt sources have been updated to include fixes for the following issues :
* Audit subsystem not resolving path name on directory watches
* audit watches do not track correctly after a rename
* auditctl output is changed in RHEL 7
* megaraid_sas: non-booting system with intel_iommu=on kernel parameter
* GFS2: kernel NULL pointer dereference in gfs2_inplace_reserve
* Crypto adapter cannot be brought online - affect all HW
* crypto/seqiv.c: wrong check of return code from crypto_rng_get_bytes
* Backport crypto: sha256_ssse3 - also test for BMI2
* NULL pointer at team_handle_frame+0x62/0x100 [team]
* AES CTR x86_64 'by8' AVX optimization
* Intel RDSEED - Fix for entropy counting
* Intel SHA1 multi-buffer crypto implementation
* Intel SHA1 AVX2 optimization support
* mlx4_en: HW timestamp ends up in error queue of socket which does not have SO_TIMESTAMPING enabled
(BZ#1213945)
All kernel-rt users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. The system must be rebooted for this update to take effect.
