CVE-2026-84546: Processing a maliciously crafted 3D model may lead to memory corruption in Apple iOS and iPadOS
A memory corruption vulnerability exists in Apple iOS and iPadOS due to an out-of-bounds write when processing maliciously crafted 3D models. This issue was addressed by improved bounds checking and fixed in iOS 26.7 and iPadOS 26.7, as well as subsequent versions. Exploiting this flaw could lead to memory corruption, potentially impacting device stability or security.
AI Analysis
Technical Summary
CVE-2026-84546 is an out-of-bounds write vulnerability in Apple iOS and iPadOS caused by improper bounds checking when processing 3D model files. This memory corruption issue could be triggered by a maliciously crafted 3D model. Apple fixed the vulnerability by improving bounds checking in iOS 26.7, iPadOS 26.7, and later versions including macOS Golden Gate 27, macOS Sequoia 15.8, macOS Tahoe 26.7, tvOS 27, visionOS 27, and watchOS 27.
Potential Impact
Successful exploitation of this vulnerability may lead to memory corruption, which can cause application crashes or potentially enable further security issues such as arbitrary code execution. However, no known exploits are reported in the wild at this time.
Mitigation Recommendations
Apply the official Apple updates to iOS 26.7, iPadOS 26.7, or later versions as these contain the fix with improved bounds checking. Devices running earlier versions are vulnerable. No additional mitigations are specified by the vendor.
