Description Srikanth Balasubramanian 2026-09-04 07:09:00 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
