CVE-2026-93195

Estado: RecibidaSin puntuar—

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

drm/bridge: synopsys: dw-dp: Support unregistering the AUX channel

The DisplayPort AUX channel gets initialized and registered during dw_dp_bind(), but it is never unregistered, which may lead to resource leaks and/or use-after-free.

Add the missing dw_dp_unbind() function to allow the users of the library to handle the required cleanup, i.e. unregister the AUX adapter.
