How to fix?

There is no fixed version for RHEL:8 kernel-debug-core.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-debug-core package and not the kernel-debug-core 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:

drivers: media: dvb-frontends/rtl2832: fix an out-of-bounds write error

Ensure index in rtl2832_pid_filter does not exceed 31 to prevent out-of-bounds access.

dev->filters is a 32-bit value, so set_bit and clear_bit functions should only operate on indices from 0 to 31. If index is 32, it will attempt to access a non-existent 33rd bit, leading to out-of-bounds access. Change the boundary check from index > 32 to index >= 32 to resolve this issue.

[hverkuil: added fixes tag, rtl2830_pid_filter -> rtl2832_pid_filter in logmsg]
