## Overview

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

drm/amdgpu/atom: Check kcalloc() for WS buffer in amdgpu_atom_execute_table_locked()

kcalloc() may fail. When WS is non-zero and allocation fails, ectx.ws
remains NULL while ectx.ws_size is set, leading to a potential NULL
pointer dereference in atom_get_src_int() when accessing WS entries.

Return -ENOMEM on allocation failure to avoid the NULL dereference.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
