Description

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