Description

A flaw was found in the Linux kernel's bcm2835-power component. An insufficient timeout during the ASB (Advanced System Bus) bridge control process, particularly under heavy system load, can prevent the V3D graphics processor from properly disabling. This can leave the V3D in an unstable state, potentially leading to system bus faults or complete system hangs, thereby impacting system availability.
