The intended byte offset would have been\n(u8 *)set_key + FRAME_DESC_SZ.\n\nThe write fires on every DISABLE_KEY callback, so plain disconnects,\nroams and interface teardowns trigger it on real networks.\n\nThe memset is redundant: the whole buffer is zeroed right after\nallocation, so the frame sent to the device is byte-identical\nwithout it. Drop the else branch; normal operation is unaffected.\n\nDiscovered by Atuin - Automated Vulnerability Discovery
