ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer overflow in _output_dell_system_info_cmc_ipv6_info in ipmi-oem/ipmi-oem-dell.c (cmc-ipv6-info subcommand to dell get-system-info).
Security readout for executives and security teams
Plain-English summary
FreeIPMI versions before 1.6.19 contain a memory-corruption flaw in a Dell system-information function. An attacker reaching the vulnerable path could potentially crash the process or compromise confidentiality and integrity. The supplied CVSS rating is 9.8, but available evidence does not confirm real-world exploitation.
Executive priority
Treat this as an urgent patching and exposure-validation item, particularly on management systems using Dell CMC queries. Prioritize upgrading exposed or frequently automated installations. Do not characterize it as an active incident solely from the critical score because exploitation has not been substantiated.
Technical view
CVE-2026-85508 is a stack-based buffer overflow, classified as CWE-121, in _output_dell_system_info_cmc_ipv6_info within ipmi-oem/ipmi-oem-dell.c. The affected path is the cmc-ipv6-info subcommand of dell get-system-info. The record identifies FreeIPMI releases before 1.6.19 as vulnerable.
Likely exposure
Exposure is most likely where FreeIPMI versions earlier than 1.6.19 are installed and ipmi-oem processes Dell CMC IPv6 information. The supplied CVSS vector describes network reachability without privileges or user interaction, but the bundle does not explain the exact attack preconditions or affected deployment configurations.
Exploitation context
The supplied CVSS 3.1 score is 9.8, with high confidentiality, integrity, and availability impact. However, the CVE is not listed as KEV, and the supplied sources provide no evidence of active exploitation, public exploit availability, or confirmed attacks.
Researcher notes
The record identifies the vulnerable function and command path but does not document the malformed input, reachable data flow, affected operating systems, or demonstrated impact. The supplied affected-version metadata is internally sparse, so validate package versions against the explicit statement that releases before 1.6.19 are affected.
Mitigation direction
Upgrade FreeIPMI to version 1.6.19 or later using trusted vendor or distribution packages.
Until upgraded, avoid the affected Dell cmc-ipv6-info operation where operationally feasible.
Restrict IPMI management communications to trusted administrative systems and networks.
Check GNU FreeIPMI and operating-system vendor guidance for platform-specific remediation details.
Validation and detection
Inventory installed FreeIPMI and ipmi-oem versions; flag every release earlier than 1.6.19.
Identify scripts, automation, or administrators using dell get-system-info with cmc-ipv6-info.
After remediation, verify each system reports FreeIPMI version 1.6.19 or later.
Review relevant process and system logs for unexplained ipmi-oem crashes, without treating absence as proof of safety.

Stack-based Buffer Overflow
Stack-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
