Memory corruption via crafted HTML rendering
Published Mar 12, 2026 · Updated Mar 12, 2026
Out-of-bounds write in Skia in Google Chrome before 146.0.7680.80 allows remote attackers to corrupt memory via crafted HTML. Google has not disclosed the affected Skia routine or the bounds-checking operation that writes beyond the target buffer. Exploitation requires a user to open attacker-controlled content; Google reports that an exploit exists in the wild, while the published record does not bound the outcome beyond memory corruption.
