Description OSIDB Bzimport 2026-05-13 16:02:26 UTC
In the Linux kernel, the following vulnerability has been resolved:

ASoC: amd: acp3x-rt5682-max9836: Add missing error check for clock acquisition

The acp3x_5682_init() function did not check the return value of
clk_get(), which could lead to dereferencing error pointers in
rt5682_clk_enable().

Fix this by:
1. Changing clk_get() to the device-managed devm_clk_get().
2. Adding proper IS_ERR() checks for both clock acquisitions.
