Linux Kernel RAA215300 Regulator Driver Resource Leak Vulnerability

A resource leak vulnerability has been identified in the Linux kernel's RAA215300 regulator driver. When the function clk_register_clkdev() is called, it allocates memory that is not properly freed in case of an error. This issue is also present with resources allocated by clk_register_fixed_rate(), which are not released during error handling. The vulnerability affects the Linux kernel stable tree.

Impact

The vulnerability can lead to a resource leak, where allocated memory and resources are not properly released, potentially causing memory exhaustion or other resource-related issues.

Remediation

The vulnerability has been addressed by modifying the driver to use managed clock registration functions that automatically handle resource cleanup. The updated driver can be found in the latest Linux kernel stable releases.
