GHSA-973H-X7W2-JGPX

Vulnerability from github – Published: 2024-05-01 15:30 – Updated: 2024-11-07 18:31

Details

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

drm/amd/display: Add 'replay' NULL check in 'edp_set_replay_allow_active()'

In the first if statement, we're checking if 'replay' is NULL. But in the second if statement, we're not checking if 'replay' is NULL again before calling replay->funcs->replay_set_power_opt().

if (replay == NULL && force_static) return false;

...

if (link->replay_settings.replay_feature_enabled && replay->funcs->replay_set_power_opt) { replay->funcs->replay_set_power_opt(replay, power_opts, panel_inst); link->replay_settings.replay_power_opt_active = power_opts; }

If 'replay' is NULL, this will cause a null pointer dereference.

Fixes the below found by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_edp_panel_control.c:895 edp_set_replay_allow_active() error: we previously assumed 'replay' could be null (see line 887)

Severity ?

4.7 (Medium)
