Cross-origin data disclosure via Skia over-read
Published Jun 30, 2026 · Updated Jun 30, 2026
Out-of-bounds read in Skia in Google Chrome before 150.0.7871.47 on macOS allows remote attackers to leak cross-origin data. Skia reads beyond an intended buffer while processing content in a crafted HTML page, exposing data across origin boundaries. Exploitation requires user interaction with the page and prior compromise of Chrome's renderer process; the reported consequence is data disclosure only.
