CVE-2017-18222

high

Description

In the Linux kernel before 4.12, Hisilicon Network Subsystem (HNS) does not consider the ETH_SS_PRIV_FLAGS case when retrieving sset_count data, which allows local users to cause a denial of service (buffer overflow and memory corruption) or possibly have unspecified other impact, as demonstrated by incompatibility between hns_get_sset_count and ethtool_get_strings.
