Description

This security bulletin contains information about 1 vulnerability.


1) Data Handling (CVE-ID: CVE-2006-5331)

CWE-ID: CWE-19 - Data Handling

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local authenticated user to perform a denial of service (DoS) attack.

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.
