There is no fixed version for RHEL:8 kernel-tools.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-tools package and not the kernel-tools package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda/cs_dsp_ctl: Use private_free for control cleanup
Use the control private_free callback to free the associated data block. This ensures that the memory won't leak, whatever way the control gets destroyed.
The original implementation didn't actually remove the ALSA controls in hda_cs_dsp_control_remove(). It only freed the internal tracking structure. This meant it was possible to remove/unload the amp driver while leaving its ALSA controls still present in the soundcard. Obviously attempting to access them could cause segfaults or at least dereferencing stale pointers.
