CVE-2017-17862

Published: Dec 23, 2017

Modified: Aug 5, 2024

PUBLISHED

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.
