An off-by-one error in the udevListInterfacesByStatus() function of libvirt can cause the libvirt daemon to crash when the number of interfaces exceeds the size of the names array. This vulnerability allows an unprivileged client to trigger a denial of service (DoS) by sending specially crafted data to the daemon. The issue does not allow privilege escalation or code execution but can disrupt virtualization services. A patch is available from Red Hat to address this issue.
AI Analysis
Technical Summary
CVE-2024-1441 is an off-by-one error vulnerability in the udevListInterfacesByStatus() function of libvirt. When the number of interfaces exceeds the size of the names array, the function can cause a segmentation fault leading to a crash of the libvirt daemon. An unprivileged attacker can exploit this by sending specially crafted data to the daemon, resulting in a denial of service condition. The vulnerability impacts availability but does not affect confidentiality or integrity. Red Hat has released a security update to fix this issue in their libvirt packages for Red Hat Enterprise Linux 9 and related products.
Potential Impact
The vulnerability allows an unprivileged local attacker to cause a denial of service by crashing the libvirt daemon, disrupting virtualization management services. There is no impact on confidentiality or integrity, and no privilege escalation or arbitrary code execution is possible. The CVSS v3.1 base score is 5.5 (medium severity) reflecting the local attack vector, low complexity, and high availability impact.
Mitigation Recommendations
A security update fixing this off-by-one error is available from Red Hat for affected libvirt packages in Red Hat Enterprise Linux 9 and related distributions. Applying the update will automatically restart the libvirt daemon to remediate the issue. No alternative mitigations are currently recommended or meet Red Hat's criteria for deployment and stability. Users should apply the official patch as soon as possible.
