Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2022-22587 is a memory corruption vulnerability resulting from insufficient input validation, assigned CWE-787. It affects iOS and iPadOS prior to version 15.3 as well as macOS Big Sur prior to 11.6.3 and macOS Monterey prior to 12.2, with a CVSS 3.1 base score of 9.8 reflecting network-accessible impact on confidentiality, integrity, and availability.
A malicious application can exploit the flaw to execute arbitrary code with kernel privileges on an unpatched device. The vulnerability requires no user interaction or special privileges beyond the ability to run the application.
Apple security updates HT213053, HT213054, and HT213055 address the issue through improved input validation in the listed releases. The advisories note that Apple is aware of reports indicating the vulnerability may have been actively exploited in the wild. The associated EPSS probability rose from a low baseline after disclosure to a peak of 0.0184 on 2023-01-01 before receding to its current value of 0.0041.
