CVE-2026-63913

The CVE-2026-63913 entry concerns the Linux kernel netfilter conntrack TCP state machine. A crafted RST with an invalid SEQ after observing a SYN could transition the conntrack entry to TCP_CONNTRACK_CLOSE, even if the RST is not a valid response to the observed SYN or its direction. This could p...
