Tech giant Microsoft released its last set of monthly security updates for 2022 with fixes for 49 vulnerabilities across its software products.

Of the 49 bugs, six are rated Critical, 40 are rated Important, and three are rated Moderate in severity. The updates are in addition to 24 vulnerabilities that have been addressed in the Chromium-based Edge browser since the start of the month.

December’s Patch Tuesday plugs two zero-day vulnerabilities, one that’s actively exploited and another issue that’s listed as publicly disclosed at the time of release.

The former relates to CVE-2022-44698 (CVSS score: 5.4), one of the three security bypass issues in Windows SmartScreen that could be exploited by a malicious actor to evade mark of the web (MotW) protections.

It’s worth noting that this issue, in conjunction with CVE-2022-41091 (CVSS score: 5.4), has been observed being exploited by Magniber ransomware actors to deliver rogue JavaScript files within ZIP archives.
