Cisco UCS M5/M6 Downfall CVE-2022-40982 Advisory

[Riaan van Niekerk]

I created this advisory because there is no central public Cisco Advisory page with all the information users would want (yet).

https://www.reddit.com/r/CiscoUCS/comments/160scwg/cisco_ucs_m5m6_downfall_cve202240982_advisory/

I will expand it as I get more information from Cisco about other/older UCS firmware releases that get the fix. Suggestions for expansion and improvement here or on Reddit are more than welcome.

Thanks, mine was not a question but sharing of content, since it does not look like Cisco will create their own advisory for this issue. In my advisory, I have linked to all the pages you linked to, the M5 & M6 reports as well as the 4.3.2 release notes. 

Also, 4.2(3h) which fixes this issue in the 4.2 release train, was released today, 28 September. I have updated my “community advisory”.
