CVE-2006-0039 (CCN-26583)

Assigned:2005-12-20
Published:2006-05-16
Updated:2023-02-13
Summary:Race condition in the do_add_counters function in netfilter for Linux kernel 2.6.16 allows local users with CAP_NET_ADMIN capabilities to read kernel memory by triggering the race condition in a way that produces a size value that is inconsistent with allocated memory, which leads to a buffer over-read in IPT_ENTRY_ITERATE.
