Linux Kernel ASoC: acp-mach-common Clock Acquisition Check
CVE-2026-43443 Published on May 8, 2026
ASoC: amd: acp-mach-common: Add missing error check for clock acquisition
In the Linux kernel, the following vulnerability has been resolved:
ASoC: amd: acp-mach-common: Add missing error check for clock acquisition
The acp_card_rt5682_init() and acp_card_rt5682s_init() functions did not
check the return values of clk_get(). This could lead to a kernel crash
when the invalid pointers are later dereferenced by clock core
functions.
Fix this by:
1. Changing clk_get() to the device-managed devm_clk_get().
2. Adding IS_ERR() checks immediately after each clock acquisition.
