Google Chromium Visuals Use-After-Free Vulnerability
Google · Chromium
A use-after-free flaw in the Visuals component of Google Chromium allows a remote attacker who has already compromised the renderer process to potentially escape the sandbox via a crafted HTML page. Exploitation requires that the renderer be compromised first and that a user visit the malicious page, with the attacker needing no prior authentication.
Use after free in Visuals in Google Chrome prior to 124.0.6367.201 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
