{"id":"AZL-92879","summary":"CVE-2026-47143 affecting package capstone 4.0.2-4","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":"2026-08-30T05:24:52Z","published":"2026-07-21T21:16:50Z","upstream":["CVE-2026-47143"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-47143"}],"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-92879.json"}}],"schema_version":"1.9.0"}
