CVE-2025-0437Network attack vector

Memory corruption via out-of-bounds Metrics read

Published Jan 15, 2025 · Updated Feb 3, 2025

Out-of-bounds read in Google Chrome Metrics before 132.0.6834.83 allows remote attackers to corrupt heap memory via crafted HTML. The Metrics component reads beyond an allocated memory boundary while handling attacker-controlled page content; the exact function remains restricted. Exposure requires Chrome to process the crafted page; successful heap corruption alters browser execution and can terminate the process.
