CVE-2025-71064 Details
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.
A vulnerability exists in the Linux kernel's handling of resource allocation for the HNS3 virtual function (VF) driver. The issue arises because the allocation of hardware queue resources does not properly initialize all elements, potentially leading to uninitialized data being used. This problem occurs because the driver's configuration can allow for more resources to be requested than are actually available, leaving some queue handles uninitialized. The vulnerability affects the Linux kernel's stable releases.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
