Published: September 17, 2026
Vulnerability details
The vulnerability allows a local privileged user to cause a resource leak.
The vulnerability exists due to a missing release of an i2c adapter reference in the drm/panel-edp panel driver when handling probe failures or driver unbinding with a devicetree ddc-i2c-bus property referring to the auxiliary ddc bus. A local privileged user can cause a panel driver probe failure or unbind to cause a resource leak.
