medium Nessus Plugin ID 339280

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the qemu packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 A flaw was found in QEMU's virtio-blk device. The issue arises because the device does not properly validate the size of input descriptors before writing data. A malicious guest with high privileges could exploit this vulnerability by submitting a malformed virtio-blk SCSI request, leading to an out-of-bounds write in the host heap memory and a potential denial of service (DoS) for the QEMU process.(CVE-2026-48914)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization qemu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected qemu packages.
