Deploy Microsoft Other update for 21170-17084, 21279-17084, 21436-17084

Linked CVEs: 3
Confirmed exploited: 0
PoC or lab evidence: 1
Maximum CVSS: 7.5

Evidence is kept separate

Confirmed exploitation, public exploit material, EPSS probability and CVSS severity answer different questions. “No confirmation recorded” means the checked sources do not currently confirm exploitation. It is not proof that exploitation has not occurred.

CVE-2026-50031 Scheduled assessment ipmi-oem in FreeIPMI before 1.6.18 has exploitable buffer overflows on response messages ipmi-oem in FreeIPMI before 1.6.18 has exploitable buffer overflows on response messages. The Intelligent Platform Management Interface (IPMI) specification defines a set of interfaces for platform management. It is implemented by a large number of hardware manufacturers to support system management. It is most commonly used for sensor reading (e.g., CPU temperatures through the ipmi-sensors command within FreeIPMI)	7.5 · CVSS 3.1 · HighSource: CNA	No confirmation recordedNo CISA KEV match was present at the last successful refresh.
