Out-of-bounds memory access via crafted HTML
Published Jul 16, 2024 · Updated Aug 6, 2024
Out-of-bounds memory access in V8 in Google Chrome before 126.0.6478.182 allows remote attackers to corrupt memory via crafted HTML. Google identifies the affected engine and bug class, but the Chromium issue remains access-restricted and no public patch detail names the faulty V8 operation. A user must load attacker-controlled HTML; the published record bounds the result to out-of-bounds memory access, with no demonstrated sandbox escape or code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <126.0.6478.182
- Affected versionversion=126.0.6478.182 <126.0.6478.182
