System-server file disclosure via path traversal
Published Jul 10, 2026 · Updated Jul 10, 2026
Path traversal in Samsung Mobile Devices before SMR Jul-2026 Release 1 allows local users to read files with system-server privilege. On Android 14, 15, and 16, the Wallpaper service insufficiently validates a supplied file path, allowing traversal beyond its intended location. Exploitation requires high local privileges; Samsung has not disclosed the vulnerable function or path parameter, and the reported impact is file disclosure only.
