Improper Branch-Pruning Logic in Linux Kernel's BPF Verifier Allows for Denial of Service

CVE-2017-17862 · MEDIUM Severity

AV:L/AC:L/AU:N/C:N/I:N/A:C

kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores unreachable code, even though it would still be processed by JIT compilers. This behavior, also considered an improper branch-pruning logic issue, could possibly be used by local users for denial of service.
