NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm-block-iscsi package and not the qemu-kvm-block-iscsi package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

A stack-buffer-overflow was found in QEMU in the NVME component. The flaw lies in nvme_changed_nslist() where a malicious guest controlling certain input can read out of bounds memory. A malicious user could use this flaw leading to disclosure of sensitive information.
