Overview
Affected versions of this package are vulnerable to Use After Free in the ttm_bo_swapout_cb process. An attacker can cause kernel memory corruption or crash the system by manipulating buffer objects and triggering swapout operations, leading to freed memory being accessed through dangling pointers. This can be achieved by allocating and freeing buffer objects in a specific sequence, forcing swapout and subsequent operations that interact with the corrupted memory.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
