Description
A flaw was found in the Linux kernel's PCIe M.2 power sequencing driver. The driver fails to release memory allocated for regulator consumer arrays during error handling and device removal. A local attacker could exploit this issue by triggering repeated device probe failures or removal operations, resulting in a memory leak that can cause a Denial of Service (DoS) through system memory exhaustion.
