Description

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix dangling pointer in plane reset function

amdgpu_dm_plane_drm_plane_reset() frees the old state before allocating a new one. If kzalloc() fails, the function returns without updating the state pointer, leaving a dangling pointer to already freed memory.

Fix this by allocating the new state first. On allocation failure, the old state remains untouched and the function safely returns.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
