VetorAV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions QEMU versions 8.0.4 and earlier
Description The issue is related to the nvme directive receive() function in the QEMU NVMe emulator, which accesses a NULL pointer because there is no check for whether an endurance group is configured before checking whether Flexible Data Placement is enabled. This can lead to a denial of service.
Recommendations For QEMU versions 8.0.4 and earlier, as a temporary workaround, consider disabling the nvme directive receive() function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
