## Description
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: flush pending RCU callbacks on module unload
Call rcu\_barrier() in module exit to wait for outstanding call\_rcu()
callbacks
before freeing module text, preventing late callback execution in freed
memory.
