CVE-2023-40445Network attack vector

Persistent lock failure via Status Bar UI handling

Published Oct 25, 2023 · Updated Feb 13, 2025

Improper security checks in Apple iOS and iPadOS before 17.1 allow attackers to prevent device locking via unspecified vectors. Apple identifies the Status Bar and improved UI handling but has not published the faulty UI operation or attacker-controlled input. The access prerequisite is undisclosed; successful exploitation leaves the device persistently unlocked rather than causing a crash or reboot.
