CVE-2026-55893

A flaw was found in Capstone, a disassembly framework. The SH floating-point decoders in arch/SH/SHDisassembler.c do not correctly validate the size of the operands array when processing certain instructions. This vulnerability allows a local attacker to provide specially crafted SH2A FPU bytecod...

Linux Distros Unpatched Vulnerability : CVE-2026-55894

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

AZL-96891 CVE-2026-55894 affecting package capstone 4.0.2-4

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...

EUVD-2026-63673

Capstone is a disassembly framework. In 6.0.0-Alpha9 and earlier, Capstone's arch/SH/SHDisassembler.c SH floating-point decoders such as opFADD, opFMUL, and opFSUB call setreg and setregn using shinfo.op.opcount without checking the fixed-size operands array. Repeated crafted instructions process...

CVE-2026-55893

Capstone (a disassembly framework) versions 6.0.0-Alpha9 and earlier contain a heap buffer overflow in the SH architecture disassembler (arch/SH/SHDisassembler.c). The SH floating-point decoders (opFADD, opFMUL, opFSUB) call set_reg() and set_reg_n() using sh_info.op.op_count without bounds-check...
