Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description In the ASoC amd acp-mach-common component, the functions acp card rt5682 init() and acp card rt5682s init() fail to check the return values of clk get(). This lack of error handling can result in a kernel crash when invalid pointers are dereferenced by clock core functions.

Recommendations Update the Linux kernel to a version where clk get() is replaced by devm clk get() and IS ERR() checks are implemented after each clock acquisition.
