CVE-2026-64765

HIGH

CVE-2026-64765 is a high-severity (CVSS 7.8) CWE-190 vulnerability in apple ipados. O3 Security detects and blocks CVE-2026-64765 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

An integer overflow was addressed with improved input validation. This issue is fixed in iOS 26.6 and iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, tvOS…

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

An integer overflow was addressed with improved input validation. This issue is fixed in iOS 26.6 and iPadOS 26.6, macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6, tvOS 26.6, visionOS 26.6, watchOS 26.6. Processing a maliciously crafted file may lead to unexpected app termination or arbitrary code execution.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every apple ipados deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

  2. Fix

    Apply the apple ipados security patch or hotfix for CVE-2026-64765 on the affected version, following the vendor advisory for your exact build.

  3. Workarounds

    Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

  4. How O3 protects you

    O3 detects and blocks CVE-2026-64765 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Tailored to CVE-2026-64765. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
