# CVE-2025-71064: net: hns3: using the num_tqps in the vf driver to apply for resources CVE-2025-71064 is fixed in 18 products on 1 platform, first by DEBIAN-CVE-2025-71064, released January 13, 2026. It is not reported as exploited. Patch Radar priority: Urgent. - Web page: https://patchblox.com/security/cve/CVE-2025-71064 - Priority: Urgent - CVSS: 9.8 (Critical) - EPSS: 0.0023 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Jan 13, 2026 - Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2025-71064 ## Description In the Linux kernel, the following vulnerability has been resolved: net: hns3: using the num_tqps in the vf driver to apply for resources Currently, hdev->htqp is allocated using hdev->num_tqps, and kinfo->tqp is allocated using kinfo->num_tqps. However, kinfo->num_tqps is set to min(new_tqps, hdev->num_tqps); Therefore, kinfo->num_tqps may be smaller than hdev->num_tqps, which causes some hdev->htqp[i] to remain uninitialized in hclgevf_knic_setup(). Thus, this patch allocates hdev->htqp and kinfo->tqp using hdev->num_tqps, ensuring that the lengths of hdev->htqp and kinfo->tqp are consistent and that all elements are properly initialized. ##
