high Tenable Self-Hosted Container Security Plugin ID 466732

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: tcp: fix TFO max_qlen accounting
across reuseport migration A listener's TCP_FASTOPEN max_qlen stops being accurate and lets through far
more pending Fast Open requests than it was configured for. This only shows up with SO_REUSEPORT listener
migration, where closing a listener hands its still-pending TFO children over to a surviving one.
fastopenq.qlen is charged in tcp_fastopen_create_child() when the child is created and uncharged in
reqsk_fastopen_remove() when the handshake completes. The uncharge follows rsk_listener of the request the
child points at, and inet_reqsk_clone() has repointed the child at a new request owned by the new
listener, so the ++ and the -- land on two different sockets. The new listener's qlen drifts negative and
its limit no longer binds. Charge the new listener during migration, like reqsk_queue_migrated() already
does for queue->young and queue->qlen. (CVE-2026-74696)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.731.2 or later.
