Summary: An update for kernel is now available for Red Hat Enterprise Linux 5.9 Long Life. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Long Life (v. 5.9 server) - i386, noarch, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: Use-after-free in snd_seq_ioctl_create_port() (CVE-2017-15265) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Bug Fix(es): * Previously, on certain Intel 64 systems, the microcode contained a new model-specific register (MSR) that was not present in the older microcode running on CPUs that had not been updated yet. As a consequence, the system crashed due to a general protection fault on a CPU running the older microcode. This update fixes the bug by having the kernel use MSR access routines that handle the general protection fault. As a result, the system no longer crashes in the described scenario. (BZ#1652467) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1501878 - CVE-2017-15265 kernel: Use-after-free in snd_seq_ioctl_create_port() 6.
