CVE-2026-3062Network attack vector

Memory corruption via Tint out-of-bounds access

Published Feb 23, 2026 · Updated Feb 23, 2026

Out-of-bounds access in Tint in Google Chrome before 145.0.7632.116 on Mac allows remote attackers to corrupt memory via crafted HTML. Tint reads from and writes to memory beyond a valid boundary, but the restricted Chromium issue does not disclose the faulty function or calculation. The attack requires a Mac user to open the crafted page and grants memory access that can expose or alter process data or crash Chrome; code execution is not established.
