To fix two of Apple’s vulnerabilities macOS Monterey 12.3.1 after posting the update macOS Big Sur and Catalina was found to be in danger. This means that about half of Mac users are vulnerable to security vulnerabilities.
macOS Monterey 12.3.1 released: Fixed two critical issues
The macOS Monterey 12.3.1 update has been shared. With the new update released by Apple, the problem of Bluetooth and external display has been fixed.
Vulnerability danger for macOS Big Sur and Catalina
Apple released macOS Monterey 12.3.1 on March 31 and fixed two zero-day vulnerabilities in the operating system. One exploit allows malicious applications to run arbitrary code, and the other to allow malicious applications to run arbitrary code. Intel Graphics allowed it to read kernel memories.
However, Apple has not released updates that close the vulnerability for macOS Big Sur or Catalina. So still running old operating systems Mac computers vulnerable to vulnerabilities is thought to be.
It is known that Apple releases macOS updates to all versions simultaneously. However, the technology giant’s latest macOS Monterey 12.3.1 update was shared alone, meaning that thousands of users were allowed to face security vulnerabilities.
For the first time since the release of macOS Monterey, Apple exploited vulnerabilities in Big Sur and Catalina ignored. Each of the previous three actively exploited vulnerabilities was patched simultaneously for Monterey, Big Sur, and Catalina.
The researchers’ latest report, Zero-day exploits of macOS Big Sur While confirming that it is still vulnerable to malware, macOS Catalina is not compromised as it is not capable of running kernel-level code.
But both Big Sur and Catalina are vulnerable to exploit that can read Intel Graphics core memories. macOS Big Sur and Catalina are stated to be safe, with the exception of two major zero-days detected earlier.
Researchers estimate that 55-60 percent of all actively used Macs are probably still running macOS Big Sur or older. That’s why hundreds of thousands of Mac users are at risk.
So what do you think about the vulnerability that threatens macOS Big Sur and Catalina? You can express your thoughts in the comments section or on the SDN Forum.
