Description

A flaw was found in the Advanced Linux Sound Architecture (ALSA) System on Chip (ASoC) AMD Audio CoProcessor (ACP) machine common driver within the Linux kernel. The `acp_card_rt5682_init()` and `acp_card_rt5682s_init()` functions failed to validate the return values from clock acquisition calls. This oversight could lead to the dereferencing of invalid pointers by clock core functions, resulting in a kernel crash and a Denial of Service (DoS) for the system.
