Microsoft fixed 126 different CVEs with this month's update (this includes the Chromium issues patched in Edge). Six of the issues were publicly disclosed, and nine are rated critical. 

Noteworthy updates:

CVE-2022-21907: This is a remote code execution vulnerability in http.sys. http.sys is part of anything in windows processing HTTP requests (e.g. IIS!). The vulnerability is exposed if the "Trailer" feature is enabled. HTTP trailers are used to delay sending headers until the end of the request (or response). They are typically used as part of chunked messages when the entire message is not known until the message has been sent. A "TE: trailers" header needs to be sent, and a "Trailer" header listing the delayed header names. This is potentially a wormable vulnerability, and Microsoft recommends prioritizing this patch. (this does not just affect IIS!). It appears that the Trailer feature is frequently enabled by default which makes this a BIG DEAL [!!! I initially assessed this as less of a risk. But a reader corrected me that the feature is enabled in server 2022, 20H2 core, and various Windows 10 and 11 versions. I misread the Microsoft announcement. This is not enabled by default in Windows Server 2019 and Windows 10 version 1809).

CVE-2022-21846: Another critical remote code execution vulnerability in Exchange. But this vulnerability is not exploitable across the internet and requires the victim and the attacker to share the same network. 

CVE-2021-22947: This vulnerability in curl was originally disclosed in September, which is why it is noted as "Publicly Disclosed". This update fixes several vulnerabilities, not just the listed CVE.
