Vulnerability from github – Published: 2025-12-16 15:30 – Updated: 2025-12-16 15:30

Details

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.
