{"id":"CVE-2024-49908","summary":"drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2)","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2)\n\nThis commit adds a null check for the 'afb' variable in the\namdgpu_dm_update_cursor function. Previously, 'afb' was assumed to be\nnull at line 8388, but was used later in the code without a null check.\nThis could potentially lead to a null pointer dereference.\n\nChanges since v1:\n- Moved the null check for 'afb' to the line where 'afb' is used.
