Out-of-bounds memory read via crafted CSS
Published Mar 4, 2026 · Updated Mar 4, 2026
Out-of-bounds read in CSS in Google Chrome before 145.0.7632.159 allows remote attackers to trigger a memory read via crafted HTML. The public advisory identifies an inappropriate CSS implementation but keeps the underlying Chromium issue restricted, so the faulty parsing operation is undisclosed. Exploitation requires a user to open the crafted page; published sources do not establish that the read data becomes visible to the attacker.
