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...

UBUNTU-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-2026-49263

Summary: CVE-2026-49263 affects Capstone’s WebAssembly backend prior to 6.0.0-Alpha9. The WASM decoder in cs_disasm() and cs_disasm_iter() can be fed attacker-controlled raw instruction bytes, and for large but well-formed br_table encodings it can mis-handle lengths (exactly 65,536), causing the...

CVE-2026-49282

Capstone (disassembly framework) vulnerability CVE-2026-49282 affects builds prior to 6.0.0-Alpha9: the cs_insn_name() API forwards caller-provided instruction IDs to architecture backends, with M68K and RISCV backends lacking sufficient bounds checks. A caller-controlled invalid instruction ID o...

Astra Linux – Vulnerability in Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, the length of Skipdata was not checked for bounds. As a result, a user-provided Skipdata callback could cause the csdisasm/csdisasmiter memcpy function to write more than 24 bytes into csinsn.bytes, leading to a heap buffe...

Astra Linux – Vulnerability in Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, a unchecked return from vsnprintf in SStreamconcat allowed a malicious csoptmem.vsnprintf to manipulate SStream’s index beyond its limit, resulting in a stack buffer underflow/overflow when the next write operation occurre...

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...
