===================================================================== Red Hat Security Advisory
Synopsis: Moderate: kernel security and bug fix update Advisory ID: RHSA-2018:3823-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:3823 Issue date: 2018-12-12 CVE Names: CVE-2017-15265 =====================================================================
1. 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()
