CVE-2026-55894

CVE-2026-55894 is an out-of-bounds read in the Capstone disassembly framework (≤ 6.0.0-Alpha9). The sh_disassemble() function in arch/SH/SHDisassembler.c computes an idx value from a raw 16-bit instruction without validating it against the active mode-specific decode[] function-pointer table. An ...

CVE-2026-55894 Capstone SH disassembler `sh_disassemble` out-of-bounds read via crafted SH2A bytecode

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...

CVE-2026-55893: Heap-based Buffer Overflow

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...

Name of the Vulnerable Software and Affected Versions Capstone versions prior to 6.0.0-Alpha10 Description The sh disassemble function in the arch/SH/SHDisassembler.c file computes an idx value from a raw 16-bit instruction without verifying if it remains within the active mode-specific decode...

SUSE CVE-2026-49263

Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's WebAssembly backend accepts attacker-controlled raw WASM instruction bytes through the public csdisasm and csdisasmiter APIs. For a large but well-formed brtable instruction, the WASM decoder accumulates the immediate...

SUSE CVE-2026-49282

Capstone is a disassembly framework. Prior to version 6.0.0-Alpha9, Capstone's public csinsnname 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...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read via the csinsnname lookup in arch/M68K/M68KInstPrinter.c and arch/RISCV/RISCVMapping.c. An attacker can crash the process by supplying an invalid instruction ID to csinsnname on an M68K or RISCV handle. On M68K, the...

Numeric Truncation Error

Overview Affected versions of this package are vulnerable to Numeric Truncation Error in readbrtable in arch/WASM/WASMDisassembler.c. An attacker can cause no-progress disassembly or parser desynchronization by supplying a large, well-formed brtable instruction through csdisasm or csdisasmiter. T...
