CVE-2006-6655: Null Pointer Dereference
First published: Wed Dec 20 2006(Updated: )
The procfs implementation in NetBSD-current before 20061023, NetBSD 3.0 and 3.0.1 before 20061024, and NetBSD 2.x before 20061029 allows local users to cause a denial of service (kernel panic) by attempting to access /emul/linux/proc/0/stat on a procfs filesystem that was mounted with mount_procfs -o linux, which results in a NULL pointer dereference.
