DESCRIPTION:
Red Hat has issued an update for kernel-rt. This fixes multiple
vulnerabilities, which can be exploited by malicious, local users in
a guest virtual machine to gain escalated privileges, by malicious,
local users to cause a DoS (Denial of Service) and gain escalated
privileges, and by malicious people to cause a DoS and compromise a
vulnerable system.

SA47488

1) An integer overflow error in the "oom_badness()" function
(mm/oom_kill.c) can be exploited to prevent a certain process from
getting terminated during OOM (Out Of Memory) condition handling and
may terminate another process.

2) An error within the software interrupt handler when preemption is
enabled can lead to CPU debug stack corruption and cause a kernel
panic.

SOLUTION:
Updated packages are available via Red Hat Network.
