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).

Multiple Vulnerabilities in FreeIPMI

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8843-1 advisory.

    It was discovered that FreeIPMI incorrectly handled certain malformed Fujitsu SEL long-text responses,     leading to a stack-based buffer overflow. An attacker in control of a malicious IPMI device could possibly     use this issue to cause FreeIPMI to crash, resulting in a denial of service, or possibly execute arbitrary     code. (CVE-2026-85504)

    It was discovered that FreeIPMI incorrectly handled short responses when retrieving Fujitsu SEL entries,     leading to a stack-based buffer over-read. An attacker in control of a malicious IPMI device could     possibly use this issue to cause FreeIPMI to crash, resulting in a denial of service. (CVE-2026-85505)

    It was discovered that FreeIPMI incorrectly handled certain Dell iDRAC and CMC IPv6 system information     responses, leading to a stack-based buffer overflow. An attacker in control of a malicious IPMI device     could possibly use this issue to cause FreeIPMI to crash, resulting in a denial of service, or possibly     execute arbitrary code. (CVE-2026-85506, CVE-2026-85508)

    It was discovered that FreeIPMI incorrectly handled certain Dell CMC system information responses, leading     to a stack-based buffer overflow. An attacker in control of a malicious IPMI device could possibly use     this issue to cause FreeIPMI to crash, resulting in a denial of service, or possibly execute arbitrary     code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS,     Ubuntu 24.04 LTS, and Ubuntu 26.04 LTS. (CVE-2026-85507)

    It was discovered that FreeIPMI incorrectly handled FRU data responses that were larger than requested,     leading to a stack-based buffer overflow. An attacker in control of a malicious IPMI device could possibly     use this issue to cause FreeIPMI to crash, resulting in a denial of service, or possibly execute arbitrary     code. (CVE-2026-85509)
