Title
drm/amdgpu/atom: Check kcalloc() for WS buffer in amdgpu_atom_execute_table_locked()
Summary
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.
Severity
No CVSS data available.
