This issue can be reproduced by sending specially crafted data to the libvirt daemon, allowing an unprivileged client to perform a denial of service attack by causing the libvirt daemon to crash.\n\n## Affected\n\n- `libvirt 9.7.0`\n- `libvirt (all versions)`\n- `libvirt`\n- `libvirt`\n- `virt:rhel/libvirt (all versions)`\n- `virt:av/libvirt (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nMitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":30.3,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[]}
