How to fix?

Upgrade SLES:15.5 kernel-macros to version 5.14.21-150500.55.127.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-macros package and not the kernel-macros package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

gfs2: Fix possible data races in gfs2_show_options()

Some fields such as gt_logd_secs of the struct gfs2_tune are accessed without holding the lock gt_spin in gfs2_show_options():

val = sdp->sd_tune.gt_logd_secs; if (val != 30) seq_printf(s, ",commit=%d", val);

And thus can cause data races when gfs2_show_options() and other functions such as gfs2_reconfigure() are concurrently executed:

spin_lock(&gt->gt_spin); gt->gt_logd_secs = newargs->ar_commit;

To fix these possible data races, the lock sdp->sd_tune.gt_spin is acquired before accessing the fields of gfs2_tune and released after these accesses.

Further changes by Andreas:

  • Don't hold the spin lock over the seq_printf operations.
