A heap buffer overflow vulnerability exists in the Capstone disassembly framework's SH floating-point decoders due to improper validation of operand array size. This flaw allows a local attacker to provide crafted SH2A FPU bytecode, potentially causing application crashes (Denial of Service) and possibly enabling arbitrary code execution. The issue affects Red Hat Hardened Images RPMs including various capstone packages. Red Hat has issued a security advisory with updated RPMs addressing these vulnerabilities. No CVSS score is provided, but the impact is significant due to potential code execution and denial of service.
