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. (NVD)
