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.

Executive Summary

This vulnerability occurs in the Linux kernel's hns3 network driver where resource allocation for transmit queue pairs (tqps) is inconsistent. Specifically, the driver uses different values to allocate arrays for hdev->htqp and kinfo->tqp, leading to some elements in hdev->htqp remaining uninitialized. This happens because kinfo->num_tqps is set to the minimum of new_tqps and hdev->num_tqps, which can be smaller than hdev->num_tqps. The patch fixes this by allocating both arrays using hdev->num_tqps, ensuring all elements are properly initialized.

Impact Analysis

The impact of this vulnerability is that uninitialized elements in the hdev->htqp array could lead to unpredictable behavior in the network driver, potentially causing system instability, crashes, or security issues related to improper resource handling. However, specific impacts such as remote code execution or data leakage are not detailed.
