DescriptionCVE.org

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in Xcode 26.4. An app may be able to cause unexpected system termination.

AnalysisAI

Xcode versions prior to 26.4 contain an out-of-bounds read vulnerability that can be triggered by local users with user interaction to cause unexpected application or system termination. This denial-of-service condition affects developers and build systems using vulnerable Xcode installations. No patch is currently available.

Technical ContextAI

The vulnerability is rooted in a classic out-of-bounds read condition, which falls under improper input validation and bounds checking mechanisms. This type of flaw typically occurs when code attempts to access memory locations beyond the allocated buffer without verifying array or string boundaries first. In the context of Xcode (Apple's integrated development environment), the affected component likely processes file data, build artifacts, or user input without adequate length validation. The CPE identifier cpe:2.3:a:apple:xcode:*:*:*:*:*:*:*:* indicates all versions of Xcode are potentially affected until version 26.4 was released. The root cause class aligns with CWE-125 (Out-of-bounds Read) or related buffer management flaws that are common in C/C++ codebases like Xcode's core components.

RemediationAI

Upgrade Apple Xcode to version 26.4 or later immediately. This is the primary and recommended fix as Apple has specifically patched the out-of-bounds read vulnerability in this release. Users and organizations should access the official Apple Xcode download page or use the Mac App Store to retrieve the latest version, following Apple's standard software update procedures. For development teams unable to upgrade immediately, implement access controls to restrict the use of vulnerable Xcode versions to isolated build environments and monitor for unexpected application terminations or crashes during development workflows. Consult Apple's support page at https://support.apple.com/en-us/126801 for detailed upgrade instructions and any supplementary guidance.
