Privileged out-of-bounds write via improper input validation
Published Jul 10, 2026 · Updated Jul 10, 2026
Improper input validation in Samsung Pass before 5.2.10.3 allows local users with high privileges to write out-of-bounds memory. Samsung has not disclosed the affected component, accepted input, or memory operation that lacks validation. Exploitation requires high local privileges and no user interaction; the established consequence is an out-of-bounds memory write.
