CVE-2022-22675
HighCVSS 7.8KEVSummary
An out-of-bounds write issue in Apple systems was addressed with improved bounds checking. This affects tvOS 15.5, watchOS 8.6, macOS Big Sur 11.6.6, macOS Monterey 12.3.1, iOS 15.4.1, and iPadOS 15.4.1. An application may execute arbitrary code with kernel privileges.
Risk Assessment
The vulnerability may be actively exploited, posing a risk of kernel-level compromise. Organizations using unpatched Apple devices are at risk.
Recommendation
Immediately update to tvOS 15.5, watchOS 8.6, macOS Big Sur 11.6.6, macOS Monterey 12.3.1, iOS 15.4.1, or iPadOS 15.4.1. Monitor devices for unusual activity.

- CVE-2026-95860Critical
In node-opcua (an OPC UA implementation for TypeScript and Node.js), versions 2.42.0 through 2.180.0 do not honor namespace-level access control configured via setDefaultRolePermissions for nodes without explicit per-node permissions. SessionContext.getApplicableRolePermissions reads a missing or null value instead of the configured namespace field, and the null result is treated permissively. As a result, an anonymous network client can write variables or call bound methods when an operator relied on restrictive namespace defaults.
