Is there a patch for CVE-2026-86950?
Yes. A fix has been recorded for CVE-2026-86950. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-86950 affect?
CVE-2026-86950 affects iOS <27 (fixed in iOS 26.7.1), iPadOS <27 (fixed in iPadOS 26.7.1), macOS Sequoia <15.8.1 (fixed in 15.8.1), macOS Tahoe <26.7.1 (fixed in 26.7.1). Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-86950?
Install Apple updates immediately; isolate/scan suspected devices and follow CISA BOD 26-04 guidance.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Processing a malicious file can trigger arbitrary code execution, allowing attackers to run code, compromise devices, and exfiltrate data.
Immediate action required
