The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - arp: Prevent overflow in arp_req_get(). syzkaller reported an overflown write in arp_req_get(). [0] When     ioctl(SIOCGARP) is issued, arp_req_get() looks up an neighbour entry and copies neigh->ha to struct     arpreq.arp_ha.sa_data. The arp_ha here is struct sockaddr, not struct sockaddr_storage, so the sa_data     buffer is just 14 bytes. In the splat below, 2 bytes are overflown to the next int field, arp_flags. We     initialise the field just after the memcpy(), so it's not a problem. However, when dev->addr_len is     greater than 22 (e.g. MAX_ADDR_LEN), arp_netmask is overwritten, which could be set as htonl(0xFFFFFFFFUL)     in arp_ioctl() before calling arp_req_get(). To avoid the overflow, let's limit the max length of     memcpy(). Note that commit b5f0de6df6dc (net: dev: Convert sa_data to flexible array in struct sockaddr)     just silenced syzkaller.
