Google: sys-kernel/cchost-kernel-6_12, sys-kernel/csql-kernel-6_12, sys-kernel/lakitu-kernel-6_12, sys-kernel/lakitu-nc-kernel-6_12: security update to 19506.448.8

critical Tenable Cloud Security Plugin ID 469179

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: ipvs: do not propagate one-packet flag
to synced conns Synced connections can be created before their destination exists. When the destination is
later added, ip_vs_bind_dest() copies connection flags from the destination into cp->flags.
IP_VS_CONN_F_ONE_PACKET connections are not synced. If a synced connection inherits
IP_VS_CONN_F_ONE_PACKET while it is already hashed, expiry can treat it as a one-packet connection and
skip unlinking the existing conn_tab node, leaving stale hash nodes pointing at a freed struct ip_vs_conn.
Drop IP_VS_CONN_F_ONE_PACKET from destination flags when binding synced connections. (CVE-2026-80714)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.448.8 or later.
