Local code execution via out-of-bounds write
Published Sep 9, 2026 · Updated Sep 10, 2026
Out-of-bounds write in Samsung Electronics libsavscmn.so before One UI 8.5 allows local users to execute arbitrary code. Samsung states only that the library lacks proper input validation; it has not disclosed the affected function, input format, or write operation. Low-privileged local access is required without user interaction, and successful exploitation runs code in the library's host-process context.
