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.
