In forEachLine of MountRegistry.cpp, there is a possible out of bounds read due to a buffer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local privilege escalation in Android's MountRegistry component across Android 14, 15, 16, and 16-qpr2 allows a low-privileged process to achieve full device compromise via a buffer overflow in the forEachLine function of MountRegistry.cpp. The flaw triggers an out-of-bounds read that can corrupt adjacent memory, enabling an attacker to elevate from a sandboxed app or low-privilege process to a higher system privilege level without any user interaction. …
