BELL-CVE-2023-53786

Affected: Alpaquita:stream: linux-lts

fkie_cve-2023-53786

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

dm flakey: fix a crash with invalid table line

This command will crash with NULL pointer dereference: dmsetup create flakey --table \ "0 `blockdev --getsize /dev/ram0` flakey /dev/ram0 0 0 1 2 corrupt_bio_byte 512"

Fix the crash by checking if arg_name is non-NULL before comparing it.
