CVE-2022-24521 [CRITICAL] Microsoft Patch Tuesday, April 2022 Edition
Microsoft on Tuesday released updates to fix roughly 120 security vulnerabilities in its Windows operating systems and other software. Two of the flaws have been publicly detailed prior to this week, and one is already seeing active exploitation, according to a report from the U.S. National Security Agency (NSA).
Of particular concern this month is CVE-2022-24521 , which is a “privilege escalation” vulnerability in the Windows common log file system driver. In its advisory, Microsoft said it received a report from the NSA that the flaw is under active attack.
“It’s not stated how widely the exploit is being used in the wild, but it’s likely still targeted at this point and not broadly available,” assessed Dustin Childs with Trend Micro’s Zero Day Initiative. “Go patch your systems before

[HIGH] Microsoft Patch Tuesday includes most vulnerabilities since Sept. 2020
Microsoft released its latest security update Tuesday, disclosing more than 140 vulnerabilities across its array of products. This is a departure from past Patch Tuesdays this year, which have only featured a few dozen vulnerabilities, and is the largest amount of issues in a single Patch Tuesday since September 2020.
Ten of these vulnerabilities are considered to be “critical,” while three others are listed as being of “moderate” severity and the remainder are considered “important.” There are also nine vulnerabilities that were first found in the Chromium web browser but affect Microsoft Edge, since it’s a Chromium-based browser. Edge users do not need to take any action to patch for these issues.
Windows Hyper-V contains three of the critical vulnerabilities patched this month — CVE-2
