Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

An out-of-bounds write vulnerability addressed through improved bounds checking affects iOS and iPadOS. The flaw is present in versions prior to iOS 15.7.1 and iPadOS 15.7.1 as well as iOS 16.1 and iPadOS 16, and it carries a CVSS score of 7.8 under CWE-787. Successful exploitation allows an application to execute arbitrary code with kernel privileges.

A local attacker can trigger the issue without special privileges when a user interacts with a malicious application, resulting in full control over the kernel and the ability to compromise confidentiality, integrity, and availability. Apple has stated that the vulnerability may have been actively exploited in the wild.

Apple security updates HT213489 and HT213490 resolve the issue by shipping the corrected versions of iOS and iPadOS. The vulnerability is also listed in CISA’s Known Exploited Vulnerabilities catalog, confirming real-world exploitation. Its EPSS score rose from a low baseline to a peak of 0.0100, indicating that exploitation interest increased after public disclosure.
