Description
A flaw was found in the Linux kernel's Direct Rendering Manager (drm/msm) component. A local attacker could trigger a deadlock vulnerability due to a circular locking dependency when the kswapd0 process attempts to reclaim memory. This can lead to a Denial of Service (DoS), causing the system to become unresponsive and unavailable.
