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 vlan_del_fail_bmap is BITS_TO_LONGS(VLAN_N_VID). It may cause out-of-bounds memory access once the VLAN id is bigger than or equal to VLAN_N_VID. Therefore, VLAN id needs to be checked to ensure it is within the range of VLAN_N_VID.
