What is CVE-2025-38011?
CVE-2025-38011 is a medium-severity memory corruption vulnerability in Linux kernel, published on 18 Jun 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
