CVE-2025-38011
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: csa unmap use uninterruptible lock
After process exit to unmap csa and free GPU vm, if signal is accepted and then waiting to take vm lock is interrupted and return, it causes memory leaking and below warning backtrace.
Change to use uninterruptible wait lock fix the issue.
(cherry picked from commit 7dbbfb3c171a6f63b01165958629c9c26abf38ab)
