Description

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.

Affected configurations

• linux linux kernel (<= 4.14.8) • debian debian linux 9.0
