A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 10 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A patch is available and has been applied to the Linux kernel to fix this issue by correcting the allocation logic. Users should update to the fixed kernel versions containing the patch to remediate this vulnerability. Since this is a Linux kernel vulnerability, the vendor manages remediation for cloud-hosted services. Check vendor advisories for confirmation and apply official updates.

Description

A vulnerability in the Linux kernel's hns3 network driver was identified where inconsistent allocation sizes for resource arrays could lead to uninitialized elements. Specifically, the vf driver used differing counts for allocating hdev->htqp and kinfo->tqp arrays, causing some elements to remain uninitialized. This issue was fixed by ensuring both arrays are allocated using the same count, hdev->num_tqps, to guarantee proper initialization.

Impact

The vulnerability could cause some elements of the hdev->htqp array to remain uninitialized, potentially leading to undefined behavior in the network driver. The exact impact is not detailed in the provided data, and no public exploits or in-the-wild exploitation are reported.

Summary

CVE-2025-71064 describes a flaw in the Linux kernel's hns3 network driver where hdev->htqp and kinfo->tqp arrays were allocated with inconsistent lengths due to differing use of num_tqps values. The vf driver set kinfo->num_tqps to the minimum of new_tqps and hdev->num_tqps, which could be smaller than hdev->num_tqps, leaving some elements of hdev->htqp uninitialized in hclgevf_knic_setup(). The patch resolves this by allocating both arrays using hdev->num_tqps, ensuring consistent lengths and full initialization of all elements.
