Overview

Affected versions of this package are vulnerable to Missing Release of Resource after Effective Lifetime in the devfreq process of the DRM MSM subsystem. An attacker can cause a resource leak by repeatedly triggering device frequency changes, leading to increased memory consumption and potential system instability.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
