AI-suggested
A patch is available and should be applied to affected linux-hwe-edge kernel versions. The fix converts the regulator management code to use devm_regulator_bulk_get_enable(), which ensures proper cleanup. Users should update to the fixed kernel versions as provided by their vendor. No additional mitigations are indicated by the vendor advisory.
Description
A vulnerability in the Linux kernel's ASoC codec driver for wcd9335 was fixed. The issue involved missing cleanup of regulator supplies during error paths and unbind operations, leading to memory leaks and unbalanced regulator enable counts. The fix involved converting the code to use devm_regulator_bulk_get_enable(), simplifying management and preventing resource leaks. This vulnerability affects specific linux-hwe-edge kernel versions. A patch is available to address this issue.
