{"id":"CVE-2024-31083","url":"https://www.cyber-defence.io/tools/cve/CVE-2024-31083","generatedAt":"2026-10-28T08:27:31.765Z","title":"A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers.","description":"A use-after-free vulnerability was found in the ProcRenderAddGlyphs() function of Xorg servers. This issue occurs when AllocateGlyph() is called to store new glyphs sent by the client to the X server, potentially resulting in multiple entries pointing to the same non-refcounted glyphs. Consequently, ProcRenderAddGlyphs() may free a glyph, leading to a use-after-free scenario when the same glyph pointer is subsequently accessed. This flaw allows an authenticated attacker to execute arbitrary code on the system by sending a specially crafted request.","published":"2024-04-05T12:15:38.000Z","lastModified":"2026-06-17T07:27:46.000Z","status":"Deferred","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-416"],"affected":[],"epss":{"score":0.01859,"percentile":0.79104,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.86%).
