Out-of-bounds heap write in QEMU's virtio-blk device allows a high-privileged guest to crash the host QEMU process. The flaw exists because the virtio-blk device omits validation of input descriptor sizes prior to writing data, enabling a malicious guest operator to submit a crafted virtio-blk SCSI request that writes beyond the allocated host heap buffer. The primary confirmed impact is a denial of service (DoS) of the QEMU process on the host; no public exploit code has been identified at time of analysis and it is not listed in the CISA KEV catalog.
