CVE-2017-17863

Assigned:2017-12-23
Published:2017-12-22
Updated:2018-03-15
Summary:kernel/bpf/verifier.c in the Linux kernel 4.9.x through 4.9.71 does not check the relationship between pointer values and the BPF stack, which allows local users to cause a denial of service (integer overflow or invalid memory access) or possibly have unspecified other impact.
