What is CVE-2023-51043?

A use-after-free vulnerability exists in the Linux kernel's GPU drivers due to a race condition occurring between nonblocking atomic commits and driver unloads. This flaw allows attackers to exploit the timing of operations between these two actions, leading to potential data corruption or system instability. The issue affects versions of the Linux kernel prior to 6.4.5, necessitating immediate patching to mitigate associated risks. Implementing the recommended updates will help secure affected systems against possible exploitation.
