Vulnerability from github – Published: 2026-01-14 15:33 – Updated: 2026-10-15 03:35In 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.
