Memory corruption via unchecked uninitialized-memory access
Published Jul 8, 2025 · Updated Jul 8, 2025
Out-of-bounds write in Samsung libsavsvc.so before Android 15 allows local users to corrupt memory through uninitialized-memory access. The library accesses uninitialized memory without a sufficient boundary check, permitting a write beyond the intended memory region. A low-privileged local context is required, and the documented consequence is memory corruption that can interrupt availability rather than disclose or modify data.
