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