CVE-2026-6068 is a critical-severity vulnerability rated 9.6/10 on the CVSS scale. 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.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
