Out-of-bounds memory access via V8 type confusion
Published Jun 11, 2024 · Updated Feb 13, 2025
Type confusion in V8 in Google Chrome before 126.0.6478.54 allows remote attackers to access memory out of bounds via crafted HTML. Google has not publicly identified the faulty V8 operation or incompatible type transition that produces the out-of-bounds access. Exploitation requires a user to load attacker-controlled HTML and can expose or alter browser-process memory or terminate the browser.
