A vulnerability in libvirt could allow an authenticated, remote attacker to escalate privileges on a targeted system.The vulnerability exists because the virtlockd-admin.socket and virtlogd-admin.socket unit files do not set the SocketMode configuration parameter in the affected software. An attacker with user access could exploit this vulnerability by connecting to the targeted system using virtlockd-admin-sock or virtlogd-admin-sock. A successful exploit could allow the attacker to bypass security restrictions and conduct further attacks.libvirt has confirmed the vulnerability and released software updates.


  • To exploit this vulnerability, the attacker must have user-level access to the targeted system. This access requirement could reduce the likelihood of a successful exploit.
