medium Tenable Self-Hosted Container Security Plugin ID 467350

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: vsock/vmci: fix sk_ack_backlog leak on
 failed handshake When vmci_transport_recv_connecting_server() returns an error,
 vmci_transport_recv_listen() calls vsock_remove_pending() but never calls sk_acceptq_removed(). This
 leaves sk_ack_backlog incremented permanently. Repeated handshake failures (malformed packets, queue pair
 alloc failure, event subscribe failure) cause sk_ack_backlog to climb toward sk_max_ack_backlog. Once it
 reaches the limit the listener permanently refuses all new connections with -ECONNREFUSED, a silent denial
 of service requiring a process restart to recover. The two existing sk_acceptq_removed() calls in
 af_vsock.c do not cover this path: line 764 checks vsock_is_pending() which returns false after
 vsock_remove_pending(), and line 1889 is only reached on successful accept(). Fix by balancing
 sk_acceptq_added() with sk_acceptq_removed() on the error path. (CVE-2026-53181)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.528.3 or later.
