Hi, The following vulnerability was published for capstone. CVE-2026-49282[0]: | 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. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
