Adjacent data access via improper transfer authentication
Published Oct 10, 2025 · Updated Oct 10, 2025
Improper authentication in Samsung Smart Switch before 3.7.66.6 allows adjacent attackers to access data during transfer. Samsung has not published the affected authentication locus or the operation that accepts an adjacent peer without proper authentication. Exploitation requires adjacency during an active transfer; the ability to alter data or interrupt the transfer is not publicly described.
