CVE-2026-17093
BMC config parsing flaw lets attackers compromise IBM Power host firmware and boot chain.
Is CVE-2026-17093 being exploited?
Not confirmed. CVE-2026-17093 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.11% probability of exploitation in the next 30 days.
How severe is CVE-2026-17093?
CVE-2026-17093 is rated High with a CVSS score of 8.2. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-17093?
Yes. A fix has been recorded for CVE-2026-17093. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-17093 affect?
CVE-2026-17093 affects IBM Power Systems FW1120.00, IBM Power Systems FW1110.00 - FW1110.30, IBM Power Systems FW1060.00 - FW1060.80, IBM Power Systems FW950.00 - FW950.H2, and 1 further product or version. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-17093?
Restrict/segregate BMC/FSP access, audit logs, apply vendor patch when released
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
With service-level BMC/FSP access, attacker can supply crafted config to corrupt host boot firmware, enabling full host compromise (code execution, data theft, integrity loss, DoS).
