CVE-2026-80714

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