Memory disclosure via unvalidated handwriting binary
Published Mar 6, 2025 · Updated Mar 6, 2025
Out-of-bounds read in Samsung Notes before 4.4.26.71 allows attackers to read process memory through handwriting content binaries. The handwriting-content processing path applies binary data without proper input validation, allowing a read beyond the intended memory buffer. Samsung scores exploitation as local with low privileges; the bounded impact is disclosure of out-of-bounds process memory, with no reported write or execution.
