LIN1023-24357 : Security Advisory - linux - CVE-2026-46214

Created: May 29, 2026    Updated: Jun 9, 2026
Found In Version: 10.23.30.2
Severity: Standard
Applicable for: Wind River Linux LTS 23
Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:  vsock/virtio: fix accept queue count leak on transport mismatch  virtio_transport_recv_listen() calls sk_acceptq_added() before vsock_assign_transport(). If vsock_assign_transport() fails or selects a different transport, the error path returns without calling sk_acceptq_removed(), permanently incrementing sk_ack_backlog.  After approximately backlog+1 such failures, sk_acceptq_is_full() returns true, causing the listener to reject all new connections.  Fix by moving sk_acceptq_added() to after the transport validation, matching the pattern used by vmci_transport and hyperv_transport.
