Linux Distros Unpatched Vulnerability : CVE-2023-3301

medium Nessus Plugin ID 227337

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - A flaw was found in QEMU. The async nature of hot-unplug enables a race scenario where the net device backend is cleared before the virtio-net pci frontend has been unplugged. A malicious guest could use this time window to trigger an assertion and cause a denial of service. (CVE-2023-3301)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
