Description OSIDB Bzimport 2026-05-13 16:02:00 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: codecs: rt1011: Use component to get the dapm context in spk_mode_put

The correct helper to use in rt1011_recv_spk_mode_put() to retrieve the
DAPM context is snd_soc_component_to_dapm(), from kcontrol we will
receive NULL pointer.
