Severity ?
Summary
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.
