CVE-2024-4558Network attack vector

Heap corruption via unsynchronized pixel-unpack state

Published May 7, 2024 · Updated Nov 4, 2025

Use-after-free in ANGLE in Google Chrome before 124.0.6367.155 allows remote attackers to corrupt heap memory via crafted HTML. The TextureGL::setCompressedSubImage path omits pixel-unpack-state synchronization before compressed texture uploads, causing some graphics drivers to read incorrect data. A user must load attacker-controlled HTML; successful heap corruption can crash the browser or enable code execution within its sandbox.
