Overview

CVE-2026-74614 is a high-severity vulnerability. It was published on August 22, 2026 and has a CVSS 3.1 base score of 8.4 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.4, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
