FAQs regarding Amazon Linux ALAS/CVE Severity

Issue Overview:

ipmi-oem in FreeIPMI before 1.6.18 has exploitable buffer overflows on response messages. The Intelligent Platform Management Interface (IPMI) specification defines a set of interfaces for platform management. It is implemented by a large number of hardware manufacturers to support system management. It is most commonly used for sensor reading (e.g., CPU temperatures through the ipmi-sensors command within FreeIPMI) and remote power control (the ipmipower command). The ipmi-oem client command implements a set of a IPMI OEM commands for specific hardware vendors. If a user has supported hardware, they may wish to use the ipmi-oem command to send a request to a server to retrieve specific information. Two subcommands "ipmi-oem dell get-active-directory-config" and "ipmi-oem fujitsu get-sel-entry-long-text" were found to have exploitable buffer overflows on response messages. (CVE-2026-50031)

FreeIPMI before 1.6.19 has a stack-based buffer overflow in _ipmi_sel_oem_fujitsu_get_sel_entry_long_text in libfreeipmi/sel/ipmi-sel-string-fujitsu-irmc-common.c via malformed Fujitsu SEL long-text responses. (CVE-2026-85504)

ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer over-read in ipmi_oem_fujitsu_get_sel_entry_long_text in ipmi-oem/ipmi-oem-fujitsu.c when a BMC provides a short response, a different vulnerability than CVE-2026-50031 (which has different affected versions). (CVE-2026-85505)

ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer overflow in _get_dell_system_info_idrac_info in ipmi-oem/ipmi-oem-dell.c (idrac-info subcommand to dell get-system-info). (CVE-2026-85506)

ipmi-oem in FreeIPMI before 1.6.19 has a stack-based buffer overflow in _output_dell_system_info_cmc_info in ipmi-oem/ipmi-oem-dell.c (cmc-info subcommand to dell get-system-info). (CVE-2026-85507)

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). (CVE-2026-85508)

FreeIPMI before 1.6.19 has a stack-based buffer overflow in _read_fru_data in libfreeipmi/fru/ipmi-fru.c when a BMC returns more bytes than requested. (CVE-2026-85509)

Issue Correction:
Run yum update freeipmi to update your system.
