Client crash via malformed OEM response parsing
Published Jun 3, 2026 · Updated Jun 3, 2026
Stack-based buffer overflows in FreeIPMI ipmi-oem before 1.6.18 allow attackers to crash the client through crafted OEM responses. The Dell parser uses a 256-byte token_data buffer for larger response data, while the Fujitsu parser accepts an unbounded data_length before copying response data. Exploitation requires a malicious IPMI device or simulator to answer either affected subcommand; the published consequence is limited to a client crash.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
