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 (CWE-787) exists in WebKit and was addressed through improved bounds checking. The issue affects Safari on macOS Monterey prior to 12.5.1, as well as iOS and iPadOS prior to 15.6.1; processing maliciously crafted web content can trigger arbitrary code execution. The flaw carries a CVSS 3.1 score of 8.8 with network attack vector, low complexity, and no required privileges beyond user interaction such as visiting a crafted page.
An attacker can exploit the flaw remotely by serving malicious web content that triggers the out-of-bounds write, achieving arbitrary code execution on the target device. Apple has stated that the vulnerability may have been actively exploited in the wild at the time of disclosure.
Updates to iOS 15.6.1, iPadOS 15.6.1, macOS Monterey 12.5.1, and Safari 15.6.1 resolve the issue. The associated EPSS score rose from a low baseline to a peak of 0.0310 in late 2024 before receding, indicating a period of increased exploitation interest well after initial disclosure.
