Summary

Security update for the Linux Kernel (Live Patch 41 for SLE 12 SP3)

Details

This update for the Linux Kernel 4.4.180-94_150 fixes several issues.

The following security issues were fixed:

CVE-2021-0935: In ip6xmit of ip6output.c, there is a possible out of bounds write due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. (bsc#1192032)
CVE-2021-28688: The fix for XSA-365 includes initialization of pointers such that subsequent cleanup code wouldn't use uninitialized or stale values. This initialization went too far and may under certain conditions also overwrite pointers which are in need of cleaning up. The lack of cleanup would result in leaking persistent grants. The leak in turn would prevent fully cleaning up after a respective guest has died, leaving around zombie domains. (bsc#1183646)
