CVE-2022-29494Network attack vector

Authenticated denial of service

Published Feb 16, 2023 · Updated Jan 27, 2025

Improper input validation in Intel OpenBMC Firmware before egs-0.91-179 and bhs-04-45 allows remote authenticated users to interrupt service. Intel has not published the affected firmware component, the accepted input, or the validation operation that mishandles it. Low-privileged network access is sufficient; the resulting BMC denial of service has no published crash, hang, or reboot mode and no confidentiality or integrity impact.
