CVE-2026-74614

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> vsock/virtio: read virtqueues under worker locks<br /> <br /> Commit bd50c5dc182b ("vsock/virtio: add support for device<br /> suspend/resume") made the *_run flags transition from false to true when<br /> restore installs replacement virtqueues. The RX, TX and event workers<br /> read their virtqueue before locking and checking the corresponding flag,<br /> so a worker delayed across freeze and restore can observe the replacement<br /> queue&amp;#39;s running state while retaining a pointer to the deleted queue.<br /> <br /> Read each virtqueue under its mutex after checking the run flag, keeping<br /> the pointer and state in the same queue generation.
