Out-of-bounds write via ANGLE integer overflow
Published Apr 1, 2026 · Updated Apr 1, 2026
Integer overflow in ANGLE in Google Chrome before 146.0.7680.178 on Windows allows remote attackers to write out of bounds. ANGLE performs an integer calculation on page-controlled data that overflows and leads to an out-of-bounds memory write; the exact calculation is undisclosed. Exploitation requires a crafted HTML page, user interaction, and prior compromise of Chrome’s renderer process; the reported consequence is bounded to the memory write.
