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.
The kernel packages contain the Linux kernel, the core of any Linux operating system.
* It was found that the Linux kernel's implementation of vectored pipe read and write functionality did not take into account the I/O vectors that were already processed when retrying after a failed atomic access operation, potentially resulting in memory corruption due to an I/O vector array overrun. A local, unprivileged user could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2015-1805, Important)
The security impact of this issue was discovered by Red Hat.
This update also fixes the following bug :
* Previously, the signal delivery paths did not clear the TS_USEDFPU flag, which could confuse the switch_to() function and lead to floating-point unit (FPU) corruption. With this update, TS_USEDFPU is cleared as expected, and FPU is no longer under threat of corruption.
(BZ#1214239)
All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.
