Local memory corruption via missing library validation
Published Sep 9, 2026 · Updated Sep 10, 2026
Out-of-bounds write in libsaviextractor.so on Samsung Mobile Devices running Android 14 through 17 allows local users to corrupt memory. Samsung states only that the library writes outside its intended memory bounds and that the patch adds validation logic; the precise input, parser path, and unchecked operation remain undisclosed. A low-privileged local user can trigger memory corruption without additional user interaction, but published evidence does not establish code execution, privilege escalation, or a reliable crash.
