Local out-of-bounds memory access via image-buffer allocation
Published Oct 10, 2025 · Updated Oct 10, 2025
Out-of-bounds read in Samsung Notes before 4.4.30.63 allows local attackers to access memory outside an allocated image buffer. The image-buffer allocation path accepts image data without proper input validation, so its buffer read can cross the allocated boundary. Local access is required; Samsung has not identified the image format or field that triggers the read, or the specific data exposed.
