Linux Distros Unpatched Vulnerability : CVE-2026-74614

high Nessus Plugin ID 338982

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- vsock/virtio: read virtqueues under worker locks Commit bd50c5dc182b (vsock/virtio: add support for device suspend/resume) made the *_run flags transition from false to true when restore installs replacement virtqueues. The RX, TX and event workers read their virtqueue before locking and checking the corresponding flag, so a worker delayed across freeze and restore can observe the replacement queue's running state while retaining a pointer to the deleted queue. Read each virtqueue under its mutex after checking the run flag, keeping the pointer and state in the same queue generation. (CVE-2026-74614)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
