A fix is available and has been applied in the Linux kernel. Users should update to the fixed kernel versions containing the patches identified by the provided commit hashes to resolve this issue.
Description
A vulnerability in the Linux kernel's drm/amdkfd component caused inconsistent trap state and reference count imbalances when copy_to_user failed during debug trap enabling. This could break subsequent disable/enable operations of the debug trap. The issue has been fixed by ensuring the trap is deactivated and the enable setup undone on failure.
