FreeIPMI: Out-of-bounds Read
CVE-2026-85505 is a high-severity out-of-bounds read vulnerability in FreeIPMI, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.6.19 as the first without the flaw, so updating FreeIPMI to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update FreeIPMI to 1.6.19 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
