Description

This security bulletin contains information about 1 vulnerability.


1) Race condition (CVE-ID: CVE-2026-74614)

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

CVSSv4: 5.7 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a race condition in virtio vsock worker handling in net/vmw_vsock/virtio_transport.c when processing virtqueue work across freeze and restore operations. A local user can trigger worker activity during suspend and restore state transitions to cause a denial of service.

The issue affects the RX, TX, and event workers when a delayed worker observes a replacement queue state while retaining a pointer to a deleted queue.
