An undersized response wraps the unsigned length difference to a very large value, and the parser then reads far past the response buffer. The affected code sits in the base (non-vendor) PLDM control class and the Huawei NCSI driver, so it is reachable for any PLDM endpoint or Huawei NIC on the internal management bus, unlike the vendor-specific wangxun parser tracked separately.\nhttps://www.cve.org/CVERecord?id=CVE-2026-65200https://www.runzero.com/advisories/huawei-malicious-device-integer-underflow-cve-2026-65200#Huawei #openBMC#CVE_2026_65200#bot", "creation_timestamp": "2026-10-13T14:50:10.630117Z"}
