An update that solves eight vulnerabilities and has 12 security fixes can now be installed.

Description:

The SUSE Linux Enterprise 12 SP5 kernel was updated.

The following security bugs were fixed:

• CVE-2022-3303: Fixed a race condition in the sound subsystem due to improper locking (bnc#1203769).
• CVE-2022-41218: Fixed an use-after-free caused by refcount races in drivers/media/dvb-core/dmxdev.c (bnc#1202960).
