Upgrade SLES:15.6 kernel-64kb-devel to version 6.4.0-150600.23.14.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64kb-devel package and not the kernel-64kb-devel package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

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

bna: ensure the copied buf is NUL terminated

Currently, we allocate a nbytes-sized kernel buffer and copy nbytes from userspace to that buffer. Later, we use sscanf on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using sscanf. Fix this issue by using memdup_user_nul instead of memdup_user.
