Description

A flaw was found in the Linux kernel's PCI subsystem. During device hot-removal, a race condition can cause the system to release a PCI bus structure while it is still referenced by an active slot. A local user capable of triggering device removal or hot-unplug operations could exploit this use-after-free condition to crash the kernel, resulting in a Denial of Service (DoS).
