Upgrade SLES:15.6 kernel-syms to version 6.4.0-150600.23.14.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-syms package and not the kernel-syms package as distributed by SLES.
See How to fix? for SLES:15.6 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
blk-cgroup: fix list corruption from resetting io stat
Since commit 3b8cc6298724 ("blk-cgroup: Optimize blkcg_rstat_flush()"), each iostat instance is added to blkcg percpu list, so blkcg_reset_stats() can't reset the stat instance by memset(), otherwise the llist may be corrupted.
Fix the issue by only resetting the counter part.
