{"id":"ALPINE-CVE-2026-34002","details":"A flaw was found in the X.Org X server. This vulnerability, an out-of-bounds read, affects the XKB (X Keyboard Extension) modifier map handling. An attacker with access to the X11 server can exploit this by sending a malformed request, which causes the server to read beyond its intended memory boundaries. This can lead to the exposure of sensitive information or cause the server to crash, resulting in a denial of service.","modified":"2026-11-03T06:32:54.798837730Z","published":"2026-05-05T16:16:11.787Z","upstream":["CVE-2026-34002"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-34002"}],"affected":[{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.22-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-34002.json"}},{"package":{"name":"xorg-server","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/xorg-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"21.1.22-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-34002.json"}},{"package":{"name":"xwayland","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/xwayland?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"24.1.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-34002.json"}},{"package":{"name":"xwayland","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/xwayland?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"24.1.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-34002.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
