An out-of-bounds heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It could occur in nvme_cmb_ops routines in a nvme device. A guest user/process could use this flaw to crash the QEMU process resulting in denial of service or, potentially, run arbitrary code with privileges of the QEMU process.
