Intel AMT / Standard Manageability firmware: Improper input validation in AMT/ISM firmware, scored high because

Impact

Improper input validation in AMT/ISM firmware, scored high because of network reach. Another entry in the recurring pattern: the out-of-band management engine keeps producing network-reachable memory-safety bugs, and each one needs an OEM firmware cycle to fix.

Who can reach it

Network access to the AMT interface on affected firmware versions.

What to do

Fixed in Intel CSME/SPS firmware, which reaches you as an OEM BIOS or firmware package - not as a microcode or OS update. That means: wait for your server vendor to ship it, drain the node, flash, and reboot. OEM availability is the long pole and routinely lags the Intel advisory by one or more quarters on server platforms. Track it per platform SKU, because vendors ship these unevenly across their own product lines.
