CVE-2022-48992

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

ASoC: soc-pcm: Add NULL check in BE reparenting

Add NULL check in dpcm_be_reparent API, to handle kernel NULL pointer dereference error. The issue occurred in fuzzing test.

This issue is fixed in RHEL-9.2 and above (including 8.10):

in (rhel-9.2, rhel-9.3, rhel-9.4, rhel-9.5, rhel-9.6) ASoC: soc-pcm: Add NULL check in BE reparenting
in (rhel-8.8, rhel-8.9, rhel-8.10) ASoC: soc-pcm: Add NULL check in BE reparenting

Please note that while RHEL-9 kernel-rt still appears as affected, it has been fixed in the same RHSA as RHEL-9 kernel. This is because from RHEL-9.3 onwards, the kernel and kernel-rt fixes are bundled together in a single errata.
