CVE-2026-6069

The NASM assembler tool is vulnerable to a stack-based buffer overflow within the disasm() function. This flaw occurs when formatting disassembly output if the slen value exceeds the allocated buffer capacity, potentially allowing an attacker to trigger an out-of-bounds write . While a proof-of-c...

capstone: Capstone: Heap buffer overflow via skipdata callback allows denial of service or arbitrary code execution.

A flaw was found in Capstone, a disassembly framework. A local attacker could exploit a heap buffer overflow vulnerability by providing a specially crafted skipdata callback. This flaw occurs because the skipdata length is not properly bounds-checked, which may allow an attacker to write beyond...

capstone: Capstone: Memory corruption via unchecked vsnprintf return

A flaw was found in Capstone, a disassembly framework. An unchecked return value from vsnprintf within the SStreamconcat function allows a malicious input to manipulate the internal stream index. This can lead to a stack buffer underflow or overflow, potentially enabling a local attacker to achie...

Medium: capstone

Issue Overview: Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, Skipdata length is not bounds-checked, so a user-provided skipdata callback can make csdisasm/csdisasmiter memcpy more than 24 bytes into csinsn.bytes, causing a heap buffer overflow in the disassembly path...
