CVE-2024-53198

Kernel crash via unreleased Xen probe resources

Published Dec 27, 2024 · Updated Aug 5, 2026

Resource-management failure in affected Linux kernel branches beginning with 2.6.23 allows local users to crash the kernel. When drv->probe() returns an error after allocating resources, xenbus_dev_probe() returns without calling drv->remove(), leaking resources and leaving a Xenstore watch tied to a freed device. The path is limited to Xen systems and requires local low-privileged influence over Xenstore, memory pressure, device hotplug, or driver rebinding; repeated failures can exhaust kernel resources or trigger an oops or panic.
