Some Huawei products use the OpenHpi software for hardware management. A function that parses data returned by OpenHpi contains an out-of-bounds read vulnerability that could lead to a denial of service. Affected product versions include: eCNS280_TD V100R005C10; eSE620X vESS V100R001C10SPC200, V100R001C20SPC200, V200R001C00SPC300.

Exploit prediction

0.59% chance of exploitation in the next 30 days, higher than 48% of all scored CVEs (FIRST EPSS, 2026-11-08).
