Linux Kernel Double Free Vulnerability in ASoC Codecs WCD9375

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.

Impact

Exploitation of this vulnerability could lead to memory corruption issues, commonly associated with double free vulnerabilities, which can be exploited to execute arbitrary code or cause a denial-of-service condition.
