CVE-2026-21079

Sensitive-data interception via unencrypted transfer channel

Published Aug 10, 2026 · Updated Aug 10, 2026

Missing encryption in Samsung Smart Switch before 3.7.72.6 allows adjacent attackers to intercept sensitive data during transfer. Samsung has not disclosed which transfer channel, protocol, or code path lacks the encryption logic. Exploitation requires low privileges, adjacent network access, and passive user interaction; the disclosed consequence is interception of data in transit.
