Cross-origin data disclosure via uninitialized ANGLE memory
Published Jun 4, 2026 · Updated Jun 4, 2026
Uninitialized memory use in ANGLE in Google Chrome before 149.0.7827.53 allows remote attackers to read cross-origin data via crafted HTML. The public record identifies ANGLE but does not disclose the affected function, allocation, or operation that consumes uninitialized data. A victim must open the attacker-controlled page; the reported consequence is cross-origin data disclosure, with no integrity or availability impact.
