Today’s mandatory Windows 11 security update fixes four bugs in the Windows Print Spooler Components: CVE-2022-21999, CVE-2022-22718, CVE-2022-21997, and CVE-2022-22717. It also fixes CVE-2022-21996, which is a Win32k Elevation of Privilege Vulnerability. “In January we saw CVE-2022-21882, a vulnerability in Win32k that was being actively exploited in the wild, which prompted CISA to issue a directive to all federal agencies to mandate that patches be applied,” Kevin Breen, Director of Cyber Threat Research, Immersive Labs, writes. The update is available via Windows Update and Microsoft Update, Windows Update for Business, Windows Server Update Services (WSUS), and Microsoft Update Catalog. Microsoft has also released Windows 11 servicing stack update 22000.460, which makes quality improvements to the servicing stack. “Servicing stack updates (SSU) ensure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft updates,” the company writes.
