CVE-2026-72020

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When a new connection is created from a malformed synchronization message, certain TCP sequence number fields may not be properly initialized. This can lead to forwarded packets containing stale data in their TCP sequence an...

CVE-2026-72020

CVE-2026-72020 affects the Linux kernel IP Virtual Server (IPVS) code. A bug in ip_vs_conn_new() caused only two ip_vs_seq members (in_seq and out_seq) to be reset, leaving init_seq and previous_delta uninitialized. For connections learned from a sync message, flags and data could be inconsistent...
