Summary
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.
