DescriptionCVE.org

The issue was addressed with improved checks. This issue is fixed in iOS 26.4 and iPadOS 26.4. A remote attacker may cause an unexpected app termination.

AnalysisAI

Unpatched denial-of-service vulnerability in Apple iOS and iPadOS allows unauthenticated remote attackers to crash applications due to insufficient input validation. The vulnerability requires no user interaction and affects all versions prior to 26.4, with no security patch currently available.

Technical ContextAI

This vulnerability resides in the iOS and iPadOS operating systems (CPE: cpe:2.3:a:apple:ios_and_ipados:*:*:*:*:*:*:*:*), indicating a system-level or bundled application component with insufficient input validation or bounds checking. The lack of assigned CWE information prevents precise root-cause classification, but the pattern of 'improved checks' in the fix suggests a classic input validation weakness, potentially related to buffer overflows (CWE-120), improper input validation (CWE-20), or null pointer dereferences (CWE-476). The remote attack vector without requiring user interaction indicates the flaw may exist in a network protocol handler, background service, or auto-invoked system component.

RemediationAI

Users and organizations must upgrade to iOS 26.4 or iPadOS 26.4 or later to patch this vulnerability. The upgrade path is through Settings > General > Software Update on affected devices, or via iTunes/Finder for macOS-managed devices. Apple provides security updates for all supported device models; verify device compatibility with iOS 26.4 availability via https://support.apple.com/en-us/126792. No workarounds are available short of patching, as the flaw exists at the OS level. Organizations managing iOS devices via MDM should create a deployment policy to roll out iOS 26.4 or later within 30 days of release to maintain security compliance. If network-level filtering is required, contact Apple Support or your MDM vendor for additional guidance, though Apple does not typically disclose specific attack patterns for closed-source OS flaws.
