Description OSIDB Bzimport 2025-02-26 03:09:27 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: rt7*-sdw: harden jack_detect_handler

Realtek headset codec drivers typically check if the card is
instantiated before proceeding with the jack detection.

The rt700, rt711 and rt711-sdca are however missing a check on the
card pointer, which can lead to NULL dereferences encountered in
driver bind/unbind tests.
