Are 35 to 40 % of all Mac computers now vulnerable to active security flaws?

Apple has not yet fixed zero-day exploits on macOS, leaving many Mac computers especially macOS Big Sur and macOS Catalina vulnerable, according to a new report. Two of the active zero-days Apple tackled include CVE-2022-22674 and CVE-2022-22675. The first exploit (CVE-2022-22674) is a ‘write bug’ that can allow malicious apps to execute arbitrary code. While the second bug, which is found in the Intel Graphics drivers, could lead to a breach of memory data.
Both of these security flaws affect macOS, but the latter also affects iOS and iPadOS, according to Joshua Long, chief security analyst at Intego.
