- Summary
- drm/amdgpu/atom: Check kcalloc() for WS buffer in amdgpu_atom_execute_table_locked()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/atom: Check kcalloc() for WS buffer in amdgpuatomexecutetablelocked()
kcalloc() may fail. When WS is non-zero and allocation fails, ectx.ws remains NULL while ectx.wssize is set, leading to a potential NULL pointer dereference in atomgetsrcint() when accessing WS entries.
Return -ENOMEM on allocation failure to avoid the NULL dereference.
