CVE-2021-30869

A type confusion vulnerability in Apple's XNU kernel allowed malicious apps to execute code with kernel privileges, and it was actively exploited in the wild.

This kernel-level vulnerability in iOS, iPadOS, and macOS enabled arbitrary code execution with elevated privileges, posing a severe risk to DIB organizations relying on Apple devices for secure operations. The fact that it was actively exploited in the wild highlights the danger of unpatched or delayed patches on widely deployed systems. DIBs must ensure rapid patching cycles and monitor for similar kernel-level flaws in their supply chain.

Shame score — A kernel-level privilege escalation flaw that was actively exploited in the wild demonstrates severe negligence in patch management and supply chain security.
