⚠️ Risk & Real-World Impact
Worst Case
Full device compromise allowing attackers to execute arbitrary code with the privileges of the vulnerable process, potentially leading to data theft, surveillance, or further network penetration.
Likely Case
App crashes or limited code execution within the sandboxed process context, potentially enabling privilege escalation or data exfiltration from the affected application.
If Mitigated
Process crash with no code execution if exploit fails or security controls like ASLR/stack protection are effective.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious image). No public exploit code identified in references.
