Libvirt: off-by-one error in udevlistinterfacesbystatus()

Published Mar 11, 2024 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
An off-by-one error flaw was found in the udevListInterfacesByStatus() function in libvirt when the number of interfaces exceeds the size of the `names` array. This issue can be reproduced by sending specially crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack by causing the libvirt daemon to crash.
