The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issue:
This update also fixes the following bugs:
A race condition existed when generating new process IDs with the result
that the wrong process could have been signaled or killed accidentally,
leading to various application faults. This update detects and disallows
the reuse of PID numbers. (BZ#638864)
When multiple JBD-based (Journaling Block Device) file systems were
mounted concurrently, and no other JBD-based file systems were already
mounted, a race could occur between JBD slab cache creation and deletion.
(BZ#645653)
A missing memory barrier caused a race condition in the AIO subsystem
between the read_events() and aio_complete() functions. This may have
caused a thread in read_events() to sleep indefinitely, possibly causing an
application hang. (BZ#638868)
Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.
