Description Johannes Segitz 2016-02-01 10:06:02 UTC 
rh#1302057

Qemu emulator built with an IDE AHCI emulation support is vulnerable to a null pointer dereference flaw. It occurs while unmapping the Frame Information Structure(FIS) & Command List Block(CLB) entries.

A privileged user inside guest could use this flaw to crash the Qemu process instance resulting in DoS.
