Vulnerability from github – Published: 2026-06-29 09:30 – Updated: 2026-06-29 09:30

Details

A flaw was found in spice-vdagent. A malicious or compromised SPICE host can trigger an integer overflow by sending a specially crafted message. This vulnerability can lead to a heap buffer overflow, causing the spice-vdagent daemon to crash and resulting in a Denial of Service (DoS) for the virtual machine. This issue requires the SPICE host to be untrusted or compromised for exploitation.

Severity

5.1 (Medium)


                  
                    CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H
