Medium severity5.5NVD Advisory· Published Dec 27, 2017· Updated Jun 17, 2026

CVE-2017-17862

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.
