   Hello,

An OOB 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 nvme devices. A 
guest user/process could use this flaw to crash the QEMU process resulting in 
DoS or potentially run arbitrary code with privileges of the QEMU process.
