macOS 11.x < 11.6.3 Multiple Vulnerabilities (HT213055)

critical Nessus Plugin ID 157242


The remote host is missing a macOS security update.


The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.6.3 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

- A memory corruption issue in IOMobileFrameBuffer that can lead to arbitrary code execution with kernel privileges due to improper input validation. (CVE-2022-22587)

- A buffer overflow issue in the kernel that can lead to arbitrary code execution with kernel privileges due to improper memory handling. (CVE-2022-22593)

- An information disclosure issue in Model I/O that can lead to unexpected application termination or arbitrary code execution due to improper state management. (CVE-2022-22579)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.


Upgrade to macOS 11.6.3 or later.
