CVE-2025-38423 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: wcd9375: Fix double free of regulator supplies Driver gets regulator supplies in probe path with devm_regulator_bulk_get(), so should not call regulator_bulk_free() in error and remove paths to avoid double free.
A double free vulnerability has been identified in the Linux kernel's ASoC codecs for the WCD9375. This issue arises because the driver improperly manages regulator supplies. During the probe phase, the driver acquires these supplies using 'devm_regulator_bulk_get()'. However, it incorrectly calls 'regulator_bulk_free()' in error and removal paths, leading to the double free condition.
