Local privilege escalation via confused-deputy file access
Published Sep 8, 2026 · Updated Sep 10, 2026
Confused-deputy flaws in Android System 16, 16-qpr2, and 17 allow local users to gain privileges through improper file access. Multiple undisclosed locations read or write files without enforcing the permissions appropriate to the caller. A local low-privileged context is required; no user interaction is needed, and exploitation permits unauthorized file reads or writes with elevated authority.
