Apple has yet to patch zero-day vulnerability for macOS Big Sur and Catalina users

With the release of macOS Monterey 12.3.1 on March 31, Apple fixed two zero-day vulnerabilities in its operating system. However, the company has not yet patched these vulnerabilities in macOS Big Sur and macOS Catalina - as those versions may be affected by the same vulnerability and are still supported by the company.

According to Apple, the vulnerability could allow a malicious application to execute arbitrary code with kernel privileges. A second vulnerability discovered in the Intel graphics driver could lead to a kernel memory leak.

While Mac users running the latest version of macOS Monterey are now safe, the same cannot be said for those who for some reason still have macOS Big Sur or macOS Catalina installed. Apple has not yet given any indication that it will release corresponding security updates for previous versions of macOS (as it usually does).

Speaking of macOS, Apple has released security updates for two previous versions of the operating system. This is because some users need more time to upgrade due to software compatibility, while others cannot upgrade their Macs because they have been discontinued by the company.

Apple announced that it will provide security updates to users staying on iOS 14. However, a few months later, the company stopped providing security patches for previous versions of iOS, forcing users to upgrade to iOS 15. In this case, all devices running iOS 14 can be upgraded to iOS 15, but there are Macs that cannot run macOS Monterey.
