GHSA-63wg-wjjj-7cp8: Zebra Address Book Aborted by IPv4-Mapped Mempool Misbehavior UpdateCVE-2026-52829 0 Zebra versions up to and including 4.4.1 running on Linux with default dual-stack IPv6/IPv4 configuration are vulnerable to a deterministic crash triggered by a remote peer. The crash occurs due to an address normalization mismatch between the handshake and mempool misbehavior paths, causing an assertion failure and process abort. An attacker can cause this by completing a P2P handshake over IPv4 and advertising an invalid mempool transaction. The vulnerability is fixed in Zebra 4.5.0 by canonicalizing addresses consistently. Workarounds include binding to an IPv4-only address or setting the Linux kernel parameter net.ipv6.bindv6only=1 to disable dual-stack acceptance.
