Process-memory disclosure via out-of-bounds font read
Published Apr 17, 2024 · Updated Feb 13, 2025
Out-of-bounds read in Chrome's Fonts component before 124.0.6367.60 allows remote attackers to read process memory via crafted HTML. The public record does not identify the specific font parser locus or the incorrect bounds operation responsible for the out-of-range read. Exploitation requires a user to open attacker-controlled HTML, and the documented consequence is disclosure of potentially sensitive process-memory data.
