Description Guilherme de Almeida Suckevicz 2026-09-21 21:00:04 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

Use after free in Skia in Google Chrome prior to 153.0.8010.47 allowed a remote attacker who had compromised the renderer process to obtain cross-origin data via a crafted HTML page. (Chromium security severity: High)
