Worst Case
A malicious application could gain root privileges, allowing complete system compromise, data theft, installation of persistent malware, or disabling of security controls.
Likely Case
Malicious applications could bypass sandbox restrictions, access protected system resources, or modify system files without proper authorization.
If Mitigated
With proper application vetting and security controls, the risk is limited to trusted applications behaving maliciously or sophisticated targeted attacks.
🎯 Exploit Status
Exploitation requires a malicious application to be executed on the target system. The logic flaw in state management suggests specific timing or race conditions may be involved.
