Linux Distros Unpatched Vulnerability : CVE-2026-55893

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 SH floating-point decoders such as opFADD, opFMUL, and...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the setregn function. An attacker can cause a four-byte heap buffer overflow by supplying crafted SH2A FPU bytecode processed through csdisasmiter or csdisasm with specific architecture and mode options,...

CVE-2026-55894

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...

DEBIAN-CVE-2026-55893

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-2026-55894

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-2026-49263

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...

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...

CVE-2026-49282 Capstone M68K and RISCV `cs_insn_name()` invalid IDs can trigger out-of-bounds reads and process crashes

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...

CVE-2026-47143

A flaw was found in the Capstone disassembly framework. This vulnerability, a null pointer dereference, can be exploited by a remote attacker. By providing a specially crafted input containing a specific 4-byte sequence during the disassembly of 3DNow! opcodes, the attacker can cause any...

AZL-93312 CVE-2026-47143 affecting package rust for versions less than 1.90.0-10

Capstone is a disassembly framework. Versions prior to 6.0.0-Alpha8 and 5.0.8 have a NULL pointer dereference in modRMRequired and decode when disassembling 3DNow! opcodes 0F 0F in builds compiled with -DCAPSTONEX86REDUCE, allowing a remote attacker to crash any application using the reduced X86...
