CVE-2026-65200

The openUBMC device-management process parses PLDM-over-MCTP and NCSI-over-MCTP responses from on-bus devices, and three response parsers in the shared transport libraries subtract a fixed header or reserved-field size from a device-supplied response length without a lower-bound check. An...

CVE-2026-65200

The openUBMC device-management process is vulnerable to an out-of-bounds heap read due to an integer underflow. Three response parsers within the shared transport libraries fail to perform a lower-bound check when subtracting a fixed header or reserved-field size from a device-supplied response l...
