Description OSIDB Bzimport 2025-05-02 16:01:56 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/edid: fix info leak when failing to get panel id

Make sure to clear the transfer buffer before fetching the EDID to
avoid leaking slab data to the logs on errors that leave the buffer
unchanged.
