CVE-2026-79241Network attack vector

Sandbox-external memory disclosure via GPU bounds error

Published Aug 25, 2026 · Updated Aug 25, 2026

Out-of-bounds read in Google Chrome on Android before 152.0.7977.65 allows remote attackers to read memory via crafted HTML. The GPU component reads beyond an allocated boundary, but Google has not disclosed the affected routine or malformed GPU data structure. A target must load attacker-controlled HTML; the bounded consequence is disclosure of memory outside the sandbox.
