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-2026-65199

openUBMC assigns the full privilege set to pseudo-identities representing SNMP callers. An authenticated, but low-privilege, SNMP user can therefore invoke mapped backend operations as an administrative identity. In routemapper/account.lua, getuserprivilege returns the complete nine-privilege set...

CVE-2026-65198

Huawei's openUBMC ships a default SNMPv3 USM key that uses one value for both authentication and privacy. An attacker who holds the key recoverable from the open-source build can authenticate SNMPv3 to, and decrypt SNMPv3 traffic from, any unit that still carries the shipped key. The build...

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...

CVE-2026-65198

Huawei's openUBMC software ships with a hard-coded default SNMPv3 USM key used for both authentication and privacy. Because these keys are shipped as constants and are not rotated by the Administrator password reset, an attacker who recovers the key from the open-source build can authenticate to ...
