Description

The issue was addressed with improved memory handling. This issue is fixed in Safari 18.6, iOS 18.6 and iPadOS 18.6, macOS Sequoia 15.6, tvOS 18.6, visionOS 2.6, watchOS 11.6. Processing maliciously crafted web content may lead to memory corruption.

Analysis

Memory corruption in WebKit browser engine allows remote code execution across Apple's ecosystem (Safari 18.6, iOS/iPadOS 18.6, macOS Sequoia 15.6, tvOS 18.6, visionOS 2.6, watchOS 11.6) when users interact with maliciously crafted web content. The vulnerability stems from improper memory handling (CWE-119 buffer overflow) and requires no authentication but user interaction to trigger. EPSS score of 0.10% (26th percentile) indicates low observed exploitation probability, and no public exploit identified at time of analysis, though the CVSS 8.8 rating reflects the potential for complete system compromise if successfully exploited.
