CVE-2026-74614

A flaw in the Linux kernel's vsock/virtio driver allows a stale pointer to a deleted virtqueue to be retained by RX, TX, or event workers during suspend/resume cycles. The root cause is a lock ordering issue introduced by commit bd50c5dc182b (device suspend/resume support): workers read their vir...
