CVE-2023-49794Public exploit

Root privilege takeover via embedded Manager APK

Published Jan 2, 2024 · Updated May 9, 2025

Authentication bypass in tiann KernelSU 0.7.1 and earlier allows local users to obtain root privileges through a crafted Android APK. The apk_sign.c path lookup in the kernel module accepts a signed Manager APK embedded in an untrusted native-library directory; incomplete path and signature checks therefore authenticate the wrong file. Exploitation requires removal of the legitimate Manager followed by installation of a nonincremental, debuggable replacement using the official Manager package identifier; successful exploitation grants root privileges.
