Description

A flaw was found in the Linux kernel's ASoC rt1011 codec component. An incorrect helper function used to retrieve the Digital Audio Power Management (DAPM) context in `rt1011_recv_spk_mode_put()` can lead to a null pointer dereference. This issue could allow a local attacker to cause a system crash, resulting in a denial of service (DoS).
