Quick emulator(Qemu) built with the SDHCI device emulation support is vulnerable
to an OOB heap access issue. It could occur while doing a multi block SDMA

A privileged user inside guest could use this flaw to crash the Qemu process
resulting in DoS or potentially execute arbitrary code with privileges of the
Qemu process on the host.
