CentOS Errata and Security Advisory CESA-2017:3315

The kernel packages contain the Linux kernel, the core of any Linux operating system.

These updated kernel packages include several security issues and numerous bug fixes, some of which you can see below. Space precludes documenting
all of these bug fixes in this advisory. To see the complete list of bug fixes, users are directed to the related Knowledge Article: https://access.redhat.com/articles/3253081

Security Fix(es):

  • It was found that the timer functionality in the Linux kernel ALSA subsystem is prone to a race condition between read and ioctl system call handlers, resulting in an uninitialized memory disclosure to user space. A local user could use this flaw to read information belonging to other users. (CVE-2017-1000380, Moderate)

Red Hat would like to thank Alexander Potapenko (Google) for reporting this issue.
