    CVE-2017-17862

    Published: 27 Dec 2017Last Modified: 16 Apr 2026

    Summary:

    Details: 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.
