{"id":"ALPINE-CVE-2026-47143","details":"Capstone is a disassembly framework. Versions prior to 6.0.0-Alpha8 and 5.0.8 have a NULL pointer dereference in `modRMRequired()` and `decode()` when disassembling 3DNow! opcodes (`0F 0F`) in builds compiled with `-DCAPSTONE_X86_REDUCE`, allowing a remote attacker to crash any application using the reduced X86 Capstone library by supplying a crafted input containing the 4-byte sequence `0F 0F \u003cmodrm\u003e \u003cimm8\u003e`. Versions 6.0.0-Alpha8 and 5.0.8 patch the issue.","modified":"2026-11-03T06:33:03.271796365Z","published":"2026-07-21T21:16:50.270Z","upstream":["CVE-2026-47143"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-47143"}],"affected":[{"package":{"name":"capstone","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/capstone?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.0.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-47143.json"}},{"package":{"name":"capstone","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/capstone?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.0.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-47143.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
