Out-of-bounds memory access via tessellation count overflow
Published Mar 4, 2026 · Updated Mar 4, 2026
Integer overflow in Skia's Ganesh GPU pipeline in Google Chrome before 145.0.7632.159 allows remote attackers to access memory out of bounds. Tessellation path accumulation adds verb counts and derives allocation sizes without first preventing integer wraparound, so crafted geometry can produce undersized GPU buffers. Exploitation requires a user to load a crafted HTML page; the published record establishes out-of-bounds memory access but does not specify whether the result is a read, write, or code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
