Detailsinfo

A vulnerability was found in IBM PowerKVM up to 3.1.0.1. It has been classified as problematic. This affects some unknown functionality of the component Linux Kernel. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

The Linux kernel component in IBM PowerKVM 2.1 before 2.1.1.3-65.10 and 3.1 before 3.1.0.2 allows guest OS users to cause a denial of service (host OS infinite loop and hang) via unspecified vectors.

The weakness was released 12/01/2016 (Website). The advisory is shared at www-01.ibm.com. This vulnerability is uniquely identified as CVE-2016-3044. The exploitability is told to be easy. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 91112 (Oracle Linux 7 : kernel (ELSA-2016-1033)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Oracle Linux Local Security Checks.
