Privileged memory disclosure via out-of-bounds read
Published Feb 4, 2025 · Updated Feb 4, 2025
Out-of-bounds read in Samsung Blockchain Keystore before 1.3.16.5 allows local users with elevated privileges to read adjacent memory. Samsung identifies improper input validation as the cause but has not published the affected function, data structure, or input-processing path. Exploitation requires privileged local access and exposes memory outside the intended buffer without a reported integrity or availability effect.
