In the Linux kernel, the following vulnerability has been resolved: drm/panfrost: Fix shrinker list corruption by madvise IOCTL Calling madvise IOCTL twice on BO causes memory shrinker list corruption and crashes kernel because BO is already on the list and it's added to the list again, while BO should be removed from the list before it's re-added. Fix it.. EPSS estimates a 0.26% chance of exploitation in the next 30 days.
