Sandbox escape via Skia heap buffer overflow
Published Apr 28, 2026 · Updated Apr 28, 2026
Heap buffer overflow in Skia in Google Chrome before 147.0.7727.138 allows remote attackers controlling a renderer to escape its sandbox. Google has not disclosed the affected Skia function or the incorrect memory operation that causes the heap overwrite beyond identifying the flaw class. Exploitation requires a compromised renderer and crafted HTML; the public record does not specify the resulting host-level capability.
