Description: | Race condition in net/packet/af_packet.c in the Linux kernel through 4.8.12 allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging the CAP_NET_RAW capability to change a socket version, related to the packet_set_ring and packet_setsockopt functions. Philip Pettersson discovered a race condition in the af_packet implementation in the Linux kernel. A local unprivileged attacker could use this to cause a denial of service (system crash) or run arbitrary code with administrative privileges.
