Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: hns3: fix oops when unload drivers paralleling<br /> <br /> When unload hclge driver, it tries to disable sriov first for each<br /> ae_dev node from hnae3_ae_dev_list. If user unloads hns3 driver at<br /> the time, because it removes all the ae_dev nodes, and it may cause<br /> oops.<br /> <br /> But we can&amp;#39;t simply use hnae3_common_lock for this. Because in the<br /> process flow of pci_disable_sriov(), it will trigger the remove flow<br /> of VF, which will also take hnae3_common_lock.<br /> <br /> To fixes it, introduce a new mutex to protect the unload process.
