Out-of-bounds memory access via type confusion
Published Sep 24, 2024 · Updated Sep 25, 2024
Type confusion in V8 in Google Chrome before 129.0.6668.70 allows remote attackers to access memory out of bounds via crafted HTML. Google has not disclosed the responsible V8 code path or the incompatible type assumption that permits the out-of-bounds access. A user must load attacker-controlled HTML; the published record establishes memory access but does not specify whether it is a read or write.

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 <129.0.6668.70
- Affected versionversion=129.0.6668.70 <129.0.6668.70
