CVE-2017-17862

Status: ModifiedMedium (5.5)—
Severity5.5Medium · CVSS 3.0
Exploitation probability0.44 %higher than 37% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

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.
