CyberRota Analysis
AI-GeneratedA vulnerability in the Linux kernel affects the IP Virtual Server (IPVS) functionality, where synced connections may incorrectly inherit the one-packet flag from their destination, leading to potential stale hash nodes pointing to freed connection structures. This could result in undefined behavior or system instability, particularly in environments relying on IPVS for load balancing. Organizations using Linux-based systems with IPVS should prioritize addressing this issue to maintain system integrity and performance.
Original NVD Description
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.
