Summary

In the Linux kernel, the HNS3 network driver lacks VLAN ID validation before use. Receiving a configuration mailbox from a VF with an invalid VLAN ID can cause out-of-bounds memory access.

Risk Assessment

An attacker could exploit this vulnerability to cause a system crash (DoS) or potentially escalate privileges through out-of-bounds memory access.

Recommendation

Immediately update the Linux kernel to a version containing the fix that adds VLAN ID validation before use in the HNS3 driver.

Original NVD description (English source)

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.
