** Description changed:

- Crafted BPF filters may crash kernel during JIT optimisation
+ The bpf_int_jit_compile function in arch/x86/net/bpf_jit_comp.c in the
+ Linux kernel before 4.0.6 allows local users to cause a denial of
+ service (system crash) by creating a packet filter and then loading
+ crafted BPF instructions that trigger late convergence by the JIT
+ compiler.
