This month's Microsoft Patch Tuesday looks like a record one, but let's look at it a bit closer to understand what is happening
The update patches a total of 243 vulnerabilities. However, 78 of them are Chromium issues affecting Microsoft Edge. Patches for Edge were released earlier. This leaves 165 vulnerabilities that are not Edge-related. Of these, 8 are rated critical, and 154 are important. One vulnerability has already been exploited, and another was made public before today but has not yet been seen in the wild.
