CVE-2017-6058 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Buffer overflow in NetRxPkt::ehdr_buf in hw/net/net_rx_pkt.c in QEMU (aka Quick Emulator), when the VLANSTRIP feature is enabled on the vmxnet3 device, allows remote attackers to cause a denial of service (out-of-bounds access and QEMU process crash) via vectors related to VLAN stripping.. EPSS estimates a 3.92% chance of exploitation in the next 30 days.
