Technical details
The vulnerability occurs when nodes stored in the validation duplicates hashtable, which come from an arena allocator, are cleared at the end of vmwexecbufprocess. While all nodes are expected to be cleared in vmwvalidationdrop_ht, certain nodes escape this process due to premature resource destruction (NVD).
Impact
The vulnerability affects the Linux kernel's graphics driver component and could potentially lead to system instability or privilege escalation due to memory corruption (NVD).
Mitigation and workarounds
The vulnerability has been addressed in the Linux kernel version 6.1.158-1~deb11u1, which includes fixes for this and numerous other security issues. Users are recommended to upgrade their linux-6.1 packages to the latest version (Debian LTS).
