AI-suggested
An official patch is available and should be applied to affected systems. The vulnerability is fixed in linux-azure kernel versions 5.15.0-1103.110~20.04.1 and later, 5.15.0-1110.119~20.04.1 and later, 5.15.0-1103.112~20.04.1 and later, 5.15.0-173.183~20.04.1 and later, and 5.15.0-1097.100~20.04.1 and later. Users should update their kernels to these or newer versions to remediate the issue.
Description
A vulnerability in the Linux kernel's hns3 network driver was resolved. The issue involved inconsistent allocation of resources in the virtual function (VF) driver, where some elements remained uninitialized due to mismatched allocation sizes. This could lead to improper initialization in the network driver. The vulnerability affects certain versions of the linux-azure kernel prior to specific patch releases. A patch is available to correct the allocation logic, ensuring all elements are properly initialized.
