There is no fixed version for RHEL:8 kernel-cross-headers.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-cross-headers package and not the kernel-cross-headers 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: firewire-lib: Avoid division by zero in apply_constraint_to_size()
The step variable is initialized to zero. It is changed in the loop, but if it's not changed it will remain zero. Add a variable check before the division.
The observed behavior was introduced by commit 826b5de90c0b ("ALSA: firewire-lib: fix insufficient PCM rule for period/buffer size"), and it is difficult to show that any of the interval parameters will satisfy the snd_interval_test() condition with data from the amdtp_rate_table[] table.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
