Use after free in DevTools in Google Chrome prior to 153.0.8010.36 allowed a remote attacker leveraging social engineering to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Use-after-free in Google Chrome's DevTools component (versions prior to 153.0.8010.36) enables arbitrary code execution within the renderer sandbox when a victim is socially engineered into visiting a crafted HTML page. The CVSS score of 8.8 reflects full C/I/A impact, but Chromium's own internal severity classification of 'Low' signals that exploitation is sandboxed - OS-level compromise requires an additional chained sandbox escape. …
