Vulnerability Name:

CVE-2006-5331 (CCN-134401)

Assigned:2006-10-16
Published:2006-10-16
Updated:2017-11-17
Summary: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.
