In the Linux kernel, the following vulnerability has been resolved: net: hns3: add VLAN id validation before using Currently, the VLAN id may be used without validation when receive a VLAN configuration mailbox from VF. The length of vlandelfailbmap is BITSTOLONGS(VLANNVID). It may cause out-of-bounds memory access once the VLAN id is bigger than or equal to VLANNVID. Therefore, VLAN id needs to be checked to ensure it is within the range of VLANN_VID.
