CVE-2026-94453

Libreswan's pluto daemon contains a use-after-free vulnerability in its IKE-over-TCP handling. The flaw occurs because the daemon retains IKE state in memory after a client closes a TCP connection; if a subsequent packet is received for the same tuple, the daemon accesses an invalid pointer to a ...

CVE-2026-94453 IKEv2 Use-After-Free bug when using IKE-over-TCP

Libreswan's pluto daemon has a use-after-free vulnerability when a client connecting using IKE over TCP closes the connection and another packet retransmit or malicious is received for the same tuple. IKE state is retained in memory after the client closes the connection, storing a pointer to...

CVE-2026-94453

A use-after-free flaw was found in Libreswan's IKE-over-TCP handling. When a TCP connection closes and additional packet processing occurs for the same connection tuple, the IKE daemon may access a previously freed interface endpoint object. A remote, unauthenticated attacker may exploit this fla...
