In QEMU 5.0.0 and earlier, es1370_transfer_audio in hw/audio/es1370.c does not properly validate the frame count, which allows guest OS users to trigger an out-of-bounds access during an es1370_write() operation.

Security readout for executives and security teams

CVE-2020-13361 is a QEMU audio device bug affecting QEMU 5.0.0 and earlier. A user inside a guest OS could trigger an out-of-bounds access through ES1370 audio emulation. The sources do not prove host compromise or active exploitation. Exposure is most relevant where QEMU 5.0.0 or earlier runs virtual machines with ES1370 audio emulation available to guests, especially multi-tenant or untrusted guest environments. Treat as a timely virtualization patching item, highest in environments hosting untrusted or tenant-controlled guests. The available evidence does not justify emergency active-exploitation handling. Mitigation focus: Update QEMU using your OS or vendor security advisory packages.; Check Debian, Ubuntu, SUSE, Gentoo, and NetApp advisories where applicable.; Review VM configurations for ES1370 audio device use..
