{"id":"DEBIAN-CVE-2026-49282","details":"Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's public `cs_insn_name()` API forwards caller-supplied instruction IDs directly to the selected architecture backend. Most backends validate the ID before indexing instruction-name tables, but the M68K and RISCV backends have missing or incomplete bounds checks. On a Capstone handle opened for M68K or RISCV, a caller-controlled invalid instruction ID can trigger an out-of-bounds read and crash the process. The demonstrated impact is availability loss in applications or bindings that expose instruction-name lookup to untrusted IDs. No code execution or data disclosure was demonstrated. Version 6.0.0-Alpha9 patches the issue.","modified":"2026-10-01T01:03:21.530890518Z","published":"2026-08-14T18:17:30.830Z","upstream":["CVE-2026-49282"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-49282"}],"affected":[{"package":{"name":"capstone","ecosystem":"Debian:12","purl":"pkg:deb/debian/capstone?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.2-5","4.0.2-5.1","5.0-1~exp1","5.0.1-1~exp1","5.0.3-1","5.0.5-1","5.0.6-1","5.0.7-1","5.0.7-1~deb13u1","5.0.7-2","5.0.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49282.json"}},{"package":{"name":"capstone","ecosystem":"Debian:13","purl":"pkg:deb/debian/capstone?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.6-1","5.0.7-1","5.0.7-1~deb13u1","5.0.7-2","5.0.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49282.json"}},{"package":{"name":"capstone","ecosystem":"Debian:14","purl":"pkg:deb/debian/capstone?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.6-1","5.0.7-1","5.0.7-1~deb13u1","5.0.7-2","5.0.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49282.json"}}],"schema_version":"1.9.0"}
