hns3 driver

About this tag
The hns3 driver is a Linux kernel network driver for HiSilicon's HNS3 Ethernet controllers, commonly used in enterprise and cloud environments. Discussions on WindowsForum.com cover critical CVEs affecting this driver, including CVE-2024-44995, which involves a deadlock due to improper locking during Traffic Control configuration, and CVE-2024-26881, a null-pointer crash triggered by Precision Time Protocol (PTP) packets on HIP08-class devices. Microsoft's Azure Linux is noted as potentially affected by these vulnerabilities, though the attestation is product-scoped. These threads highlight the importance of patching the hns3 driver to maintain network stability and security in Linux-based systems, particularly in Azure deployments.

  1. CVE-2024-44995: HNS3 Deadlock and Azure Linux Attestation

    Microsoft’s short, one‑line attestation that “Azure Linux includes this open‑source library and is therefore potentially affected” is accurate — but it is a product‑scoped inventory statement, not a universal guarantee that no other Microsoft product contains the same vulnerable Linux kernel...

  2. CVE-2024-26881: Kernel patch fixes hns3 PTP null pointer crash in HiSilicon NICs

    A small but important kernel fix — tracked as CVE-2024-26881 — plugs a null‑pointer crash in the Linux hns3 network driver that can be triggered when Precision Time Protocol (PTP/1588) packets arrive for HIP08-class HiSilicon devices. Microsoft’s published guidance for the CVE explicitly states...
