Memory corruption via unchecked buffer index
Published Sep 2, 2026 · Updated Sep 3, 2026
An out-of-bounds write in Samsung Open Source TizenFX allows local users to corrupt memory through the MediaBufferBase indexer setter. The setter writes through a caller-supplied array index without checking that the index remains within the backing buffer's bounds. Exploitation requires low-privileged local access and a high-complexity condition; successful use can alter memory or crash the affected process.
