{"id":"AZL-95982","summary":"CVE-2026-49282 affecting package capstone 4.0.2-4","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":"2026-08-30T05:24:52Z","published":"2026-08-14T18:17:30Z","upstream":["CVE-2026-49282"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49282"}],"affected":[{"package":{"name":"capstone","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/capstone"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.0.2-4"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-95982.json"}}],"schema_version":"1.9.0"}
