Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
The kernel-rt packages contain the Linux kernel, the core of any Linux operating system.
* A NULL pointer dereference flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system. (CVE-2014-5077, Important)
* Multiple use-after-free flaws and an integer overflow flaw were found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled user controls. A local, privileged user could use either of these flaws to crash the system. (CVE-2014-4653, CVE-2014-4654, CVE-2014-4655, CVE-2014-4656, Moderate)
* An information leak flaw was found in the way the Linux kernel's Advanced Linux Sound Architecture (ALSA) implementation handled access of the user control's state. A local, privileged user could use this flaw to leak kernel memory to user space. (CVE-2014-4652, Low)
This update also fixes the following bug :
* Prior to this update, the netconsole module was unavailable on MRG Realtime kernels due to locking issues that disabled it. These locking issues have been corrected, allowing the netconsole module to be re-enabled and functional on Realtime kernels.
(BZ#1088923)
Users are advised to upgrade to these updated packages, which upgrade the kernel-rt kernel to version kernel-rt-3.10.33-rt32.45 and correct these issues. The system must be rebooted for this update to take effect.
