Bug 137625 – Kernel: linux ppc 32 user triggerable DoS (CVE-2006-2448)

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Sune Kloppenborg Jeppesen (RETIRED) 2006-06-22 11:02:37 UTC]

This fixes a bug found by Dave Jones that means that it is possible
 for userspace to provoke a machine check on 32-bit kernels.  This
 also fixes a couple of other places where I found similar problems
 by inspection.
