Description Agostino Sarubbo gentoo-dev 2017-06-04 13:45:08 UTC
From ${URL} :

Quick emulator built with the IDE AHCI Emulation support is vulnerable to a
host memory leakage issue. It could occur while hot-unplugging the AHCI device.

A privileged user inside guest could use this flaw to leak host memory
resulting in DoS.
