Security update for the Linux Kernel (Live Patch 11 for SLE 15 SP2)
Notes
Title of the patch
Security update for the Linux Kernel (Live Patch 11 for SLE 15 SP2)
Description of the patch
This update for the Linux Kernel 5.3.18-24_52 fixes several issues.
The following security issues were fixed:
- CVE-2021-3444: Fixed an issue with the bpf verifier which did not properly handle mod32 destination register truncation when the source register was known to be 0 leading to out of bounds read (bsc#1184171).
- CVE-2021-28660: Fixed an out of bounds write in rtw_wx_set_scan (bsc#1183658).
- CVE-2021-28688: Fixed an issue introduced by XSA-365 (bsc##1182294, bsc#1183646).
