| CVE-2016-5008 | Cri | 0.64 | 9.8 | 0.04 | Jul 13, 2016 | libvirt before 2.0.0 improperly disables password checking when the password on a VNC server is set to an empty string, which allows remote attackers to bypass authentication and establish a VNC session by connecting to the server. | ||
| CVE-2017-1000256 | Hig | 0.53 | 8.1 | 0.02 | Oct 31, 2017 | libvirt version 2.3.0 and later is vulnerable to a bad default configuration of "verify-peer=no" passed to QEMU by libvirt resulting in a failure to validate SSL/TLS certificates by default. | ||
| CVE-2018-6764 | Hig | 0.51 | 7.8 | 0.00 | Feb 23, 2018 | util/virlog.c in libvirt does not properly determine the hostname on LXC container startup, which allows local guest OS users to bypass an intended container protection mechanism and execute arbitrary commands via a crafted NSS module. | ||
| CVE-2018-1064 | Hig | 0.49 | 7.5 | 0.03 | Mar 28, 2018 | libvirt version before 4.2.0-rc1 is vulnerable to a resource exhaustion as a result of an incomplete fix for CVE-2018-5748 that affects QEMU monitor but now also triggered via QEMU guest agent. | ||
| CVE-2018-5748 | Hig | 0.49 | 7.5 | 0.03 | Jan 25, 2018 | qemu/qemu_monitor.c in libvirt allows attackers to cause a denial of service (memory consumption) via a large QEMU reply. | ||
| CVE-2014-3672 | Med | 0.42 | 6.5 | 0.00 | May 25, 2016 | The qemu implementation in libvirt before 1.3.0 and Xen allows local guest OS users to cause a denial of service (host disk consumption) by writing to stdout or stderr. | ||
| CVE-2015-5247 | Med | 0.42 | 6.5 | 0.01 | Apr 14, 2016 | The virStorageVolCreateXML API in libvirt 1.2.14 through 1.2.19 allows remote authenticated users with a read-write connection to cause a denial of service (libvirtd crash) by triggering a failed unlink after creating a volume on a root_squash NFS pool. | ||
| CVE-2024-4418 | Med | 0.40 | 6.2 | 0.00 | May 8, 2024 | A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in the virNetClientIOEventLoop() method, the `data` pointer to a stack-allocated virNetClientIOEventData structure ended up being used in the virNetClientIOEventFD callback… | ||
| CVE-2024-2494 | Med | 0.40 | 6.2 | 0.00 | Mar 21, 2024 | 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… | ||
| CVE-2011-4600 | Med | 0.38 | 5.9 | 0.02 | Apr 14, 2016 | The networkReloadIptablesRules function in network/bridge_driver.c in libvirt before 0.9.9 does not properly handle firewall rules on bridge networks when libvirtd is restarted, which might allow remote attackers to bypass intended access restrictions via a (1) DNS or (2) DHCP… | ||
| CVE-2025-13193 | Med | 0.36 | 5.5 | 0.00 | Nov 17, 2025 | A flaw was found in libvirt. External inactive snapshots for shut-down VMs are incorrectly created as world-readable, making it possible for unprivileged users to inspect the guest OS contents. This results in an information disclosure vulnerability. | ||
| CVE-2025-12748 | Med | 0.36 | 5.5 | 0.00 | Nov 11, 2025 | A flaw was discovered in libvirt in the XML file processing. More specifically, the parsing of user provided XML files was performed before the ACL checks. A malicious user with limited permissions could exploit this flaw by submitting a specially crafted XML file, causing… | ||
| CVE-2024-1441 | Med | 0.36 | 5.5 | 0.00 | Mar 11, 2024 | 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… | ||
| CVE-2015-5160 | Med | 0.36 | 5.5 | 0.00 | Aug 20, 2018 | libvirt before 2.2 includes Ceph credentials on the qemu command line when using RADOS Block Device (aka RBD), which allows local users to obtain sensitive information via a process listing. | ||

| CVE-2013-2218 | 0.04 | — | 0.08 | Sep 30, 2013 | Double free vulnerability in the virConnectListAllInterfaces method in interface/interface_backend_netcf.c in libvirt 1.0.6 allows remote attackers to cause a denial of service (libvirtd crash) via a filtering flag that causes an interface to be skipped, as demonstrated by the… | |||
| CVE-2009-0036 | 0.03 | — | 0.01 | Feb 11, 2009 | Buffer overflow in the proxyReadClientSocket function in proxy/libvirt_proxy.c in libvirt_proxy 0.5.1 might allow local users to gain privileges by sending a portion of the header of a virProxyPacket packet, and then sending the remainder of the packet with crafted values in the… | |||
| CVE-2024-8235 | 0.00 | — | 0.00 | Aug 30, 2024 | A flaw was found in libvirt. A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent… | |||
| CVE-2024-2496 | 0.00 | — | 0.00 | Mar 18, 2024 | A NULL pointer dereference flaw was found in the udevConnectListAllInterfaces() function in libvirt. This issue can occur when detaching a host interface while at the same time collecting the list of interfaces via virConnectListAllInterfaces API. This flaw could be used to… | |||
| CVE-2023-2700 | 0.00 | — | 0.00 | May 15, 2023 | A vulnerability was found in libvirt. This security flaw ouccers due to repeatedly querying an SR-IOV PCI device's capabilities that exposes a memory leak caused by a failure to free the virPCIVirtualFunction array within the parent struct's g_autoptr cleanup. |
