Security Bulletin
This security bulletin contains one medium risk vulnerability.
EUVDB-ID: #VU62739
Risk: Medium
CVSSv4.0: 4.3 [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/E:U/U:Green]
CVE-ID: CVE-2022-0897
CWE-ID:
CWE-667 - Improper Locking
Exploit availability: No
DescriptionThe 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).
MitigationUpdate the affected package libvirt to the latest version.
