Description Pedro Sampaio 2018-03-08 18:26:13 UTC

In the Linux kernel, 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.

An upstream patch:
