CVE-2024-53183

Kernel panic via unavailable network driver data

Published Dec 27, 2024 · Updated May 11, 2026

A release-path flaw in the Linux User-Mode Linux network driver allows local users to crash the kernel by removing a network device. The net_device_release function obtains uml_net through dev_get_drvdata after driver data is unavailable, dereferencing an invalid pointer instead of deriving the containing object. The flaw is confined to a User-Mode Linux instance, requires low-privileged local access, and causes a kernel panic rather than data disclosure or modification.
