freeipmi vulnerabilities

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)
