- Summary
- CVE-2026-55894 affecting package capstone 4.0.2-4
- Details
-
Capstone is a disassembly framework. In 6.0.0-Alpha9 and earlier, Capstone's arch/SH/SHDisassembler.c shdisassemble() function computes an idx value from a raw 16-bit instruction without ensuring it is within the active mode-specific decode[] function-pointer table. An application using CSARCHSH with CSMODESH2A or CSMODESH4A and CSMODESHFPU can pass crafted bytecode through csdisasmiter() or csdisasm(), causing the decode[idx] test to read outside the table and terminate the process with a segmentation fault. No code execution or information disclosure was demonstrated. This issue is fixed in version 6.0.0-Alpha10.
