Doc Text:
A flaw was found in NASM, a Netwide Assembler. This vulnerability, known as a heap use after free, occurs when the program attempts to use memory that has already been released. During response file processing, a pointer to freed memory is retained and later accessed. This can lead to data corruption or unexpected program behavior.

Description OSIDB Bzimport 2026-04-10 14:01:39 UTC
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 unexpected behavior.
