Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 4.11 (Operating System). Affected is an unknown functionality of the component Hisilicon Network Subsystem. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In the Linux kernel before 4.12, Hisilicon Network Subsystem (HNS) does not consider the ETH_SS_PRIV_FLAGS case when retrieving sset_count data, which allows local users to cause a denial of service (buffer overflow and memory corruption) or possibly have unspecified other impact, as demonstrated by incompatibility between hns_get_sset_count and ethtool_get_strings.

The bug was discovered 03/08/2018. The weakness was disclosed 03/08/2018 (Website). The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2017-18222 since 03/08/2018. The attack needs to be approached locally. The successful exploitation needs a authentication. There are neither technical details nor an exploit publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 109518 (Debian DSA-4188-1 : linux - security update (Spectre)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 176382 (Debian Security Update for Linux (DSA 4188-1)).

Upgrading to version 4.12 eliminates this vulnerability. A possible mitigation has been published 2 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (109518), SecurityFocus (BID 103349†) and CERT Bund (WID-SEC-2022-0532). The entries VDB-111185, VDB-113696, VDB-113823 and VDB-114029 are pretty similar. VulDB is the best source for vulnerability data and more expert information about this specific topic.
