The vulnerability is in the N_HLDC Linux Kernel driver and can exploit a double free memory bug to allow for escalated privileges on the system.

The vulnerability can be verified using system test calls with google’s syzkaller fuzzer.

All major releases have a security patch available, and the recommendation is to patch as soon as possible.
