Summary
The DNAv4 protocol implementation in the DHCP component in Apple iOS before 6 sends Wi-Fi packets containing a MAC address of a host on a previously used network, which might allow remote attackers to obtain sensitive information about previous device locations by sniffing an unencrypted Wi-Fi network for these packets.
Exploit prediction
0.75% chance of exploitation in the next 30 days, higher than 55% of all scored CVEs (FIRST EPSS, 2026-11-09).
