Improper locking in libvirt - CVE-2022-0897

Vulnerability identifier: #VU62739

CSH Severity: Medium

CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-0897

CWE-ID: CWE-667

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local user to perform a denial of service attack (DoS).

The vulnerability exists due to double-locking error within the nwfilterConnectNumOfNWFilters() function in nwfilter/nwfilter_driver.c in libvirt. An local user can abuse the libvirt API virConnectNumOfNWFilters to crash the network filter management daemon (libvirtd/virtnwfilterd).
