CVE-2024-2494 (GCVE-0-2024-2494)

Vulnerability from cvelistv5 – Published: 2024-03-21 13:39 – Updated: 2026-02-25 19:31

Title

Libvirt: negative g_new0 length can lead to unbounded memory allocation

Summary

A flaw was found in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before the non-negative length check is performed by the C API entry points. Passing a negative length to the g_new0 function results in a crash due to the negative length being treated as a huge positive number. This flaw allows a local, unprivileged user to perform a denial of service attack by causing the libvirt daemon to crash.

Severity ?

CVE-2024-1441 (GCVE-0-2024-1441)

Vulnerability from cvelistv5 – Published: 2024-03-11 13:37 – Updated: 2025-11-08 08:05

Title

Libvirt: off-by-one error in udevlistinterfacesbystatus()

Summary

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.

Severity ?

5.5 (Medium)
