Linux Kernel up to 5.2.x Marvell Wifi Chip Driver buffer overflow

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Upgrading the affected component is recommended.

Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 5.2.x (Operating System). This affects an unknown code block of the component Marvell Wifi Chip Driver. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.

The weakness was disclosed 09/20/2019 (Website). The advisory is shared at lists.fedoraproject.org. This vulnerability is uniquely identified as CVE-2019-14816 since 08/10/2019. An attack has to be approached locally. The requirement for exploitation is a authentication. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 208574 (CentOS 7 : kernel-alt (RHSA-2020:0174)), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 5.3.0 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (208574). The entries VDB-140692, VDB-140765 and VDB-142076 are pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
