CVE-2023-53060

Local system hang via nested teardown lock

Published May 2, 2025 · Updated May 23, 2026

Improper locking in the Linux kernel igb driver allows local users to hang a system during SR-IOV device teardown. igb_disable_sriov takes rtnl_lock during device removal, then unregister_netdev in the igbvf removal path tries to acquire the same lock and deadlocks. Reachability requires local access and an igb device using SR-IOV; the documented consequence is an availability-only kernel hang during teardown.
