CVE-2026-43480 Details
Description
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.
A vulnerability exists in the Linux kernel's ACP3X RT5682 MAX9836 audio driver. The issue arises because the 'acp3x_5682_init()' function fails to verify the return value of 'clk_get()', potentially leading to the dereferencing of error pointers in 'rt5682_clk_enable()'. This vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed by modifying the driver to use 'devm_clk_get()', a device-managed function that automatically handles clock resource management. Additionally, proper error checks have been implemented for both clock acquisitions.
