Vulnerability Title
Capstone M68K and RISCV `cs_insn_name()` invalid IDs can trigger out-of-bounds reads and process crashes
Vulnerability Description
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.

Vulnerability Title
Capstone Engine 缓冲区错误漏洞
Vulnerability Description
Capstone Engine是Capstone Engine组织开源的一套反汇编引擎框架。 Capstone Engine 6.0.0-Alpha9之前版本存在安全漏洞,该漏洞源于cs_insn_name() API将调用者提供的指令ID直接传递给架构后端,M68K和RISCV后端缺失或不完整的边界检查,可能导致越界读取和进程崩溃。
