CVE-2016-7907: Qemu

Medium severity, CVSS 4.4. EPSS: 0.4% chance of exploitation in the next 30 days.

The imx_fec_do_tx function in hw/net/imx_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags.

Affected products
