Overview

CVE-2006-5331 is a medium-severity vulnerability. It was published on October 29, 2017 and has a CVSS 3.0 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.0 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

The altivec_unavailable_exception function in arch/powerpc/kernel/traps.c in the Linux kernel before 2.6.19 on 64-bit systems mishandles the case where CONFIG_ALTIVEC is defined and the CPU actually supports Altivec, but the Altivec support was not detected by the kernel, which allows local users to cause a denial of service (panic) by triggering execution of an Altivec instruction.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
