CVE-2024-53181

Local kernel crash via stale release drvdata

Published Dec 27, 2024 · Updated May 11, 2026

A release-path flaw in the Linux kernel's UML vector driver allows local users to crash affected kernels by removing a vector device. The vector_device_release function calls dev_get_drvdata after driver data is unavailable, then dereferences the resulting invalid vector_device pointer instead of deriving the enclosing object. Local low-privileged access to a User Mode Linux instance with a removable vector network device is required, and successful triggering causes a kernel panic rather than data disclosure or modification.
