Macs running macOS Sequoia before 15.7.8 are exposed to the listed flaws, and some need a local app or a malicious file rather than a remote attacker. The sources do not state how CVE-2026-43665 is triggered, so the specific exposure of this CVE is unknown. Machines already on 15.7.8 or a later build are not affected by the patched issues.
