Description
A flaw was found in the Linux kernel. A local user can trigger a Denial of Service (DoS) when attempting to unmount a filesystem after its underlying storage device has been disconnected while in use. During cleanup, the kernel repeatedly rescans cached file metadata structures without making progress while holding locks. This behavior blocks subsequent filesystem operations and causes system tasks to hang, rendering the system unresponsive.
