red hat
Calendar Grey February 26, 2019
Dist Redhat Esm H88
CentOS 7 has launched a crucial kernel security patch along with various bug resolutions. Discover the potential effects today.
An update for kernel is now available for Red Hat Enterprise Linux 6

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.

Summary

The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* kernel: MIDI driver race condition leads to a double-free (CVE-2018-10902)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* Previously backported upstream patch caused a change in the behavior of page fault handler. As a consequence, applications compiled through GNU Compiler Collection (GCC) version 4.4.7 sometimes generated stack access exceeding the 64K limit. Running such applications subsequently triggered a segmentation fault. With this update, the 64k limit check in the page fault handler has been removed. As a result, running the affected applications no longer triggers the segmentation fault in the described scenario.
Note that removing the limit check does not impact the integrity of the kernel itself. (BZ#1644401)
