Vulnerability from fkie_nvd - Published: 2006-05-19 22:02 - Updated: 2026-06-16 22:19
Severity
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.
