First published: Mon Jul 28 2014(Updated: )

The kernel packages contain the Linux kernel, the core of any Linux<br>operating system.<br><li> It was found that the Linux kernel's ptrace subsystem allowed a traced</li> process' instruction pointer to be set to a non-canonical memory address<br>without forcing the non-sysret code path when returning to user space.<br>A local, unprivileged user could use this flaw to crash the system or,<br>potentially, escalate their privileges on the system. (CVE-2014-4699,<br>Important)<br>Note: The CVE-2014-4699 issue only affected systems using an Intel CPU.<br>Red Hat would like to thank Andy Lutomirski for reporting this issue.<br>All kernel 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>
