CVE-2024-10604Public exploitNetwork attack vector

Cross-site device tracking via predictable header values

Published Jan 30, 2025 · Updated Feb 24, 2025

Network-header randomness flaws in Fuchsia before F16 and F17 through F19 allow remote attackers to derive stable device identifiers. The gVisor-based network stack uses a 31-bit Go PRNG, invertible Jenkins hashes, undersized hash keys, and collision-prone IP ID tables to populate TCP and IP fields. The demonstrated tracking path runs site JavaScript and observes generated headers to recover identifiers across sites, networks, and private-browsing sessions.
