MiracleLinux 4 : kernel-2.6.32-573.22.1.el6 (AXSA:2016-195:03)
medium Nessus Plugin ID 288942
Synopsis
The remote MiracleLinux host is missing a security update.Description
The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2016-195:03 advisory.The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.
Security issues fixed with this release:
CVE-2016-0774
** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.
Fixed bugs:
* In the anon_vma structure, the degree counts number of child anon_vmas and of VMAs which points to this anon_vma. Failure to decrement the parent's degree in the unlink_anon_vma() function, when its list was empty, previously triggered a BUG_ON() assertion. The provided patch makes sure the anon_vma degree is always decremented when the VMA list is empty, thus fixing this bug.
* When running Internet Protocol Security (IPSEC) on external storage encrypted with LUKS under a substantial load on the system, data corruptions could previously occur. A set of upstream patches has been provided, and data corruption is no longer reported in this situation.
* Due to prematurely decremented calc_load_task, the calculated load average was off by up to the number of CPUs in the machine. As a consequence, job scheduling worked improperly causing a drop in the system performance. This update keeps the delta of the CPU going into NO_HZ idle separately, and folds the pending idle delta into the global active count while correctly aging the averages for the idle-duration when leaving NO_HZ mode. Now, job scheduling works correctly, ensuring balanced CPU load.
* Due to a regression in the Asianux Server 6.7 kernel, the cgroup OOM notifier accessed a cgroup-specific internal data structure without a proper locking protection, which led to a kernel panic. This update adjusts the cgroup OOM notifier to lock internal data properly, thus fixing the bug.
* GFS2 had a rare timing window that sometimes caused it to reference an uninitialized variable.
Consequently, a kernel panic occurred. The code has been changed to reference the correct value during this timing window, and the kernel no longer panics.
* Due to a race condition whereby a cache operation could be submitted after a cache object was killed, the kernel occasionally crashed on systems running the cachefilesd service. The provided patch prevents the race condition by adding serialization in the code that makes the object unavailable. As a result, all subsequent operations targetted on the object are rejected and the kernel no longer crashes in this scenario.
Enhancements:
* The lpfc driver has been updated to version 11.0.0.4.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
