NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu package and not the qemu package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

QEMU (aka Quick 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) and Command List Block (CLB) entries. A privileged user inside guest could use this flaw to crash the QEMU process instance resulting in DoS.
