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.","epss":{"date":"2026-11-05","percentile":0.01443,"score":0.00113},"exploits":[],"kev":null,"metrics":[{"score":5.1,"severity":"medium","source":"CNA: redhat","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:H","version":"3.1"}],"modifiedAt":1793917013039,"publishedAt":1782719619079,"references":[{"source":"CNA: redhat","tags":["vdb-entry","x_refsource_REDHAT"],"url":"https://access.redhat.com/security/cve/CVE-2026-57965"},{"source":"CNA: redhat","tags":["issue-tracking","x_refsource_REDHAT"],"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2493581"}],"remediation":[],"revision":"c66a395c2a4b9c1e841e5e3f6daf0407a233d46e491e48a8b33a25a171c50580","sources":[{"modifiedAt":1793917013039,"name":"CNA: redhat","retrievedAt":1793920117125,"url":"https://www.cve.org/CVERecord?id=CVE-2026-57965"},{"modifiedAt":null,"name":"FIRST EPSS","retrievedAt":1793920127342,"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-57965"}],"ssvc":{"assessedAt":1782729781020,"automatable":"no","exploitation":"none","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"Spice-vdagent: integer overflow in udscs_write() leading to heap buffer overflow","updatedAt":1793920127342}
