libvirt

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.

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.

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 to perform a denial of service attack by causing the libvirt daemon to crash.

CVE-2024-1441 is a medium-severity vulnerability identified in libvirt version 9.7.0, specifically within the udevListInterfacesByStatus() function. The issue is an off-by-one error that arises when the number of network interfaces exceeds the allocated size of the 'names' array used internally by this function. This boundary error can be triggered by an unprivileged client sending specially crafted data to the libvirt daemon, which manages virtualization capabilities on Linux systems. The flaw causes the daemon to crash, resulting in a denial of service condition. The vulnerability affects the availability of the libvirt service but does not compromise confidentiality or integrity. Exploitation requires local access with low privileges (AV:L/PR:L), no user interaction (UI:N), and the attack scope is unchanged (S:U). The CVSS 3.1 vector is AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H, reflecting that the attack is local, requires low privileges, and leads to high impact on availability. No known public exploits or patches are currently documented, but the issue has been officially published and reserved since February 2024. This vulnerability is particularly relevant for environments running libvirt 9.7.0 managing multiple network interfaces, such as cloud providers, virtualization hosts, and enterprise data centers.
