Linux kernel-rt is vulnerable to denial of service. An integer overflow flaw was found in the way the Linux kernel’s netfilter connection tracking implementation loaded extensions. An attacker on a local network could potentially send a sequence of specially crafted packets that would initiate the loading of a large number of extensions, causing the targeted system in that network to crash.
