GHSA-4R2G-J5RC-7WQF

Vulnerability from github – Published: 2022-03-26 00:00 – Updated: 2024-04-01 15:30

Details

A flaw was found in the libvirt nwfilter driver. The virNWFilterObjListNumOfNWFilters method failed to acquire the driver->nwfilters mutex before iterating over virNWFilterObj instances. There was no protection to stop another thread from concurrently modifying the driver->nwfilters object. This flaw allows a malicious, unprivileged user to exploit this issue via libvirt’s API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd).

Severity ?

4.3 (Medium)
