Amazon Linux 2 : libvirt, --advisory ALAS2-2026-3873 (ALAS-2026-3873)
The version of libvirt installed on the remote host is prior to 4.5.0-36. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3873 advisory. libvirt: newline injection in network xml dns txt/srv fields allows dnsmasq config directive injection CVE-2026-61477...
PT-2026-83377
A symlink-following flaw was found in libvirt's qemuTPMEmulatorPrepareHost function. The function uses a path-based chown on the swtpm logfile without checking for symbolic links. A local attacker with access to the swtpm account can replace the logfile with a symlink, causing libvirtd running as...
OPENSUSE-SU-2026:11622-1 libvirt-12.6.0-2.1 on GA media

Astra Linux – Vulnerability in libvirt
A “off-by-one” error flaw was discovered in the udevListInterfacesByStatus function in libvirt, where 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 to perform a...
Astra Linux – Vulnerability in libvirt
A flaw was discovered in libvirt. A refactoring of the code that retrieves 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 could lead to a NULL pointer being dereferenced, causing the...
Astra Linux – Vulnerability in libvirt
A flaw was discovered in libvirt during its generation of SELinux MCS category pairs for virtual machines’ dynamic labels. This flaw allows one exploited guest to access files labeled for another guest, resulting in the breach of sVirt confinement. The greatest threat posed by this vulnerability...
Astra Linux – Vulnerability in libvirt
A flaw was discovered in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before performing the negative length check by the C API entry points. Passing a negative length to the gnew0 function results in a crash because the negative length is treate...
Astra Linux – Vulnerability in libvirt
The vulnerability of the virsocketaddr.c component in the Libvirt virtualization management library is related to a numerical overflow condition. Exploiting this vulnerability allows an attacker to cause a service failure remotely...
Astra Linux – Vulnerability in libvirt
A issue was discovered in qemuDomainGetStatsIOThread in qemu/qemudriver.c within libvirt version 4.10.0 through 6.x, prior to 6.1.0. A memory leak was identified in the virDomainListGetStats libvirt API, which is responsible for retrieving domain statistics when managing QEMU guests. This flaw...
Astra Linux – Vulnerability in libvirt
A improper locking issue was detected in the virStoragePoolLookupByTargetPath API of libvirt. This issue occurs in the storagePoolLookupByTargetPath function, where a locked virStoragePoolObj object is not properly released in case of an ACL permission failure. Clients connecting to the read-writ...
Astra Linux – Vulnerability in libvirt
A flaw was discovered 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 prevent another thread from concurrently modifying the driver-nwfilters object...
