CVE-2026-43443

Summary

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.
