Worst Case
Successful exploitation could enable privilege escalation or arbitrary code execution in kernel context by chaining with other vulnerabilities.
Likely Case
Information disclosure about kernel memory layout, making subsequent exploitation of other vulnerabilities easier.
If Mitigated
Limited information disclosure with no direct code execution capability.
🎯 Exploit Status
Exploitation requires local app execution and likely needs to be chained with other vulnerabilities for full impact.
