Summary
Red Hat Security Advisory: kernel-rt security update
Notes
Topic
Updated kernel-rt packages that fix one security issue are now available
for Red Hat Enterprise MRG 2.
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.
Details
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
* A use-after-free flaw was found in the way the Linux kernel's key
management subsystem handled keyring object reference counting in certain
error path of the join_session_keyring() function. A local, unprivileged
user could use this flaw to escalate their privileges on the system.
(CVE-2016-0728, Important)
Red Hat would like to thank the Perception Point research team for
reporting this issue.
All kernel-rt users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. The system must be
rebooted for this update to take effect.
