CVE-2026-28994

Adjacent-network denial of service via Wi-Fi use-after-free

Published May 11, 2026 · Updated May 11, 2026

Use-after-free in Apple operating-system Wi-Fi handling allows attackers to interrupt affected devices via crafted Wi-Fi packets. The Wi-Fi component accesses memory after its lifetime ends while processing a crafted packet; Apple has not identified the responsible function or object. Exploitation requires a privileged network position and causes denial of service, with no reported data disclosure, modification, or code execution.
