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.

A vulnerability classified as critical has been found in IBM AIX and VIOS (Operating System) (version now known). Affected is some unknown processing of the component X11. The manipulation with an unknown input leads to a buffer overflow vulnerability. CWE is classifying the issue as CWE-120. The program 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. CVE summarizes:

IBM AIX 7.1, 7.2, 7.3 and VIOS , 3.1 could allow a non-privileged local user to exploit a vulnerability in X11 to cause a buffer overflow that could result in a denial of service or arbitrary code execution. IBM X-Force ID: 243556.

The weakness was disclosed 01/19/2023. The advisory is shared for download at This vulnerability is traded as CVE-2022-47990 since 12/28/2022. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 02/15/2023). It is expected to see the exploit prices for this product decreasing in the near future.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at X-Force (243556).
