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.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability occurs in the Linux kernel's amdgpu driver where, after a process exits and attempts to unmap the csa and free the GPU virtual memory, if a signal is accepted and the waiting to take the vm lock is interrupted and returns, it causes memory leaking and a warning backtrace. The issue was fixed by changing to use an uninterruptible wait lock.


How can this vulnerability impact me? :

The vulnerability can cause memory leaks in the system when the affected amdgpu driver code is executed, potentially leading to resource exhaustion or instability in systems using the affected Linux kernel version with AMD GPU drivers.
