Vulnerability from github – Published: 2026-01-14 15:33 – Updated: 2026-07-14 15:31

Details

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.

Severity

7.1 (High)

No race or uncontrollable condition is required.\nPR:L - The attacker needs control of an assigned VF but no PF or host administrative privilege or mailbox authentication. Delegated VF access is a low privilege in the originating tenant scope.\nUI:N - The PF processes the VF mailbox command automatically without any victim action.\nS:C - An untrusted VM or workload can control the VF while the malformed request corrupts the host PF kernel, crossing the tenant-to-host security boundary.\nC:H - The 16-bit ID reaches roughly 7.5 KiB beyond the bitmap into adjacent pointers and structures. The resulting corruption can enable host-kernel code execution and arbitrary memory disclosure.\nI:H - Invalid delete and add requests provide selected bit-set and bit-clear operations over adjacent kernel data, enabling pointer corruption and potentially host-kernel code execution.\nA:H - The repeatable out-of-bounds atomic memory operations can corrupt or fault kernel memory, directly causing a host kernel oops, panic, or hang."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
