Security vulnerability: Regression in SUSE Linux Enterprise 15 SP3 kernel caused by RETBLEED fixes
This document (000020704) is provided subject to the disclaimer at the end of this document.
If this kernel has already been installed and is causing problems:
1. boot the buggy kernel with the following boot command line option to disable the buggy mitigation:
spectre_v2=off2. When the default multi-version setup is available, the previous kernel will still be installed, and the buggy one can be de-installed:
rpm -q kernel-defaultshould show 2 or more lines. Either boot the previous kernel and/or de-install the buggy one with
zypper rm kernel-default-5.3.18-150300.59.81.13. When only 1 kernel is installed, install the previous kernel release 5.3.18-150300.59.76.1, with e.g.:
zypper in -f kernel-default-5.3.18-150300.59.76.1
