| Subject: CVE-2022-49182: net: hns3: add vlan list lock to protect vlan list |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: hns3: add vlan list lock to protect vlan list |
| |
| When adding port base VLAN, vf VLAN need to remove from HW and modify |
| the vlan state in vf VLAN list as false. If the periodicity task is |
| freeing the same node, it may cause "use after free" error. |
| This patch adds a vlan list lock to protect the vlan list. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49182 to this issue. |
