Remote code execution with the same privileges as the Chrome process, potentially leading to full system compromise, data theft, or ransomware deployment.
Likely Case
Browser crash (denial of service) or limited code execution within the Chrome sandbox, potentially enabling data exfiltration or further exploitation.
If Mitigated
Browser crash with no data loss if sandboxing works correctly and no additional vulnerabilities are chained.
🎯 Exploit Status
Use-after-free vulnerabilities typically require some exploitation expertise but are commonly weaponized. The high CVSS score suggests reliable exploitation is possible.
