Memory Leak in Ath12k Linux Kernel Driver Affecting QCN9274 Hardware

CVE-2023-53767

What is CVE-2023-53767?

A memory leak vulnerability has been identified in the Ath12k Linux kernel driver, specifically affecting systems utilizing the QCN9274 hardware. The issue arises when the driver fails to properly free a buffer associated with event handling if the ATH12K_FLAG_UNREGISTERING flag is activated. This oversight may lead to inefficient memory utilization over time. A recent patch has been implemented to address this flaw, ensuring that memory is appropriately managed and preventing the accumulation of leaked resources.
