Title
drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2)
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Add null check for 'afb' in amdgpu_dm_update_cursor (v2)
This commit adds a null check for the 'afb' variable in the
amdgpu_dm_update_cursor function. Previously, 'afb' was assumed to be
null at line 8388, but was used later in the code without a null check.
This could potentially lead to a null pointer dereference.
Changes since v1:
- Moved the null check for 'afb' to the line where 'afb' is used. (Alex)
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:8433 amdgpu_dm_update_cursor()
error: we previously assumed 'afb' could be null (see line 8388)
Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
