Use after free in V8 in Google Chrome prior to 153.0.8010.47 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Use-after-free in the V8 JavaScript engine of Google Chrome desktop builds prior to 153.0.8010.47 allows unauthenticated remote attackers to execute arbitrary code inside the renderer sandbox when a victim loads a crafted HTML page. Because the CVSS vector is PR:N/UI:R, no credentials or special browser configuration are required, but the victim must actively navigate to attacker-controlled content; the memory-corruption primitive is confined to the renderer process, so full host compromise would require a second, independent sandbox-escape vulnerability. …
