Description OSIDB Bzimport 2025-10-01 08:02:47 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: remove oem i2c adapter on finish

Fixes a bug where unbinding of the GPU would leave the oem i2c adapter
registered resulting in a null pointer dereference when applications try
to access the invalid device.

(cherry picked from commit 89923fb7ead4fdd37b78dd49962d9bb5892403e6)
