CVE-2015-4700 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.45% chance of exploitation in the next 30 days.
