Out-of-bounds memory access via crafted CSS
Published Mar 24, 2026 · Updated Mar 24, 2026
Out-of-bounds read in CSS in Google Chrome before 146.0.7680.165 allows remote attackers to access memory via a crafted HTML page. The CSS component reads beyond a memory boundary while processing attacker-controlled page content; Google has not disclosed the affected routine or malformed construct. Exploitation requires a user to open the attacker-controlled page, and public sources describe no demonstrated consequence beyond out-of-bounds memory access.
