Status: ModifiedHigh (7.8)—
Severity7.8High · CVSS 3.1
Exploitation probability0.39 %higher than 32% 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 allows local users to cause a denial of service (integer overflow and memory corruption) or possibly have unspecified other impact by leveraging unrestricted integer values for pointer arithmetic.
