Description
A flaw was found in the Linux kernel's Display Processing Unit (DPU) driver. During DPU runtime suspend, a mismatch can occur between the power rail voltage and the core clock frequency. This happens when the power management attempts to drop the voltage while the clock remains at its highest rate. This inconsistency can lead to system instability or a crash, effectively causing a Denial of Service (DoS).
