Tracked as CVE-2020-9859, the vulnerability was found in the iOS kernel and it can allow an application to achieve unsandboxed, kernel-level code execution.
An exploit for the issue was added to the unc0ver 5.0 jailbreak utility, which was released to support devices running iOS 11 through 13.5 (excluding versions 12.3-12.3.2 and 12.4.2-12.4.5).
In an alert published last week, the CERT Coordination Center warned that the security flaw might also impact modern iOS devices with CPUs that support Pointer Authentication Code (PAC).
