CVE-2026-6069

NASM’s disasm() function contains a stack based buffer overflow when formatting disassembly output, allowing an attacker triggered out-of-bounds write when `slen` exceeds the buffer capacity.

CVE-2026-6068

NASM contains a heap use after free vulnerability in response file (-@) processing where a dangling pointer to freed memory is stored in the global depend_file and later dereferenced, as the response-file buffer is freed before the pointer is used, allowing for data corruption or remote code execution.

CVE-2026-6067

A heap buffer overflow vulnerability exists in the Netwide Assembler (NASM) due to a lack of bounds checking in the obj_directive() function. This vulnerability can be exploited by a user assembling a malicious .asm file, potentially leading to heap memory corruption, denial of service (crash), and arbitrary code execution.

NASM Netwide Assember parser.c parse_line stack-based overflow

A vulnerability has been found in NASM Netwide Assember 2.17rc0. Affected is the function parse_line of the file parser.c. The manipulation leads to stack-based buffer overflow. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used.

NASM Netwide Assember nasm.c assemble_file stack-based overflow

A vulnerability was identified in NASM Netwide Assember 2.17rc0. This issue affects the function assemble_file of the file nasm.c. The manipulation leads to stack-based buffer overflow. It is possible to launch the attack on the local host. The exploit has been disclosed to the public and may be used.

NASM Netwide Assember preproc.c parse_smacro_template null pointer dereference

A vulnerability was determined in NASM Netwide Assember 2.17rc0. This vulnerability affects the function parse_smacro_template of the file preproc.c. The manipulation leads to null pointer dereference. Attacking locally is a requirement. The exploit has been disclosed to the public and may be used.

NASM Netwide Assember outmacho.c macho_no_dead_strip heap-based overflow

A vulnerability was found in NASM Netwide Assember 2.17rc0. This affects the function macho_no_dead_strip of the file outmacho.c. The manipulation leads to heap-based buffer overflow. Local access is required to approach this attack. The exploit has been disclosed to the public and may be used.

NASM Netwide Assember preproc.c do_directive use after free

A vulnerability has been found in NASM Netwide Assember 2.17rc0. Affected by this issue is the function do_directive of the file preproc.c. The manipulation leads to use after free. An attack has to be approached locally. The exploit has been disclosed to the public and may be used.
