NVD Description

Note: Versions mentioned in the description apply only to the upstream libvirt-daemon-driver-nodedev package and not the libvirt-daemon-driver-nodedev package as distributed by SLES. See How to fix? for SLES:15.5 relevant fixed versions and status.

A flaw was found in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before the non-negative length check is performed by the C API entry points. Passing a negative length to the g_new0 function results in a crash due to the negative length being treated as a huge positive number. This flaw allows a local, unprivileged user to perform a denial of service attack by causing the libvirt daemon to crash.
