Descriptions
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.
kernel/bpf/verifier.c en el kernel de Linux hasta la versión 4.14.8 ignora el código inalcanzable, incluso aunque sea procesado por compiladores en tiempo de ejecución o JIT. Este comportamiento, que también se considera un problema de lógica de poda de ramas incorrecta, podría ser utilizado por usuarios locales para provocar una denegación de servicio (DoS).
