AnalysisAIv1 – Sep 15, 2026

Connecting an Apple device to an attacker-controlled NFS server can cause the kernel NFS client to mishandle memory and return out-of-bounds kernel memory to the malicious server, an information-disclosure issue tracked as CVE-2026-43687. All shipping Apple platforms are affected — iOS/iPadOS before 26.7 and 27, macOS Tahoe before 26.7, macOS Golden Gate before 27, and tvOS, visionOS and watchOS before 27 — while the fix is distributed across Apple's 26.7/27 update wave. Exploitation requires the victim to initiate a connection to the hostile server (UI:R), which keeps real-world risk moderate: EPSS is only 0.18% (7th percentile), CISA KEV does not list it, SSVC rates exploitation as 'none' and automatable as 'no', and no public exploit code was identified at time of analysis.
