RHSA-2016:0068: Important: kernel-rt security update
First published: Tue Jan 26 2016(Updated: )
The kernel packages contain the Linux kernel, the core of any Linux<br>operating system.<br><li> A use-after-free flaw was found in the way the Linux kernel's key</li> management subsystem handled keyring object reference counting in certain<br>error path of the join_session_keyring() function. A local, unprivileged<br>user could use this flaw to escalate their privileges on the system.<br>(CVE-2016-0728, Important)<br>Red Hat would like to thank the Perception Point research team for<br>reporting this issue.<br>All kernel-rt users are advised to upgrade to these updated packages, which<br>contain a backported patch to correct this issue. The system must be<br>rebooted for this update to take effect.<br>
