CVE-2026-44056: Stack Buffer Overflow Dirent Dname
A directory entry name (`d_name`) is copied or concatenated into a fixed-size stack buffer using unsafe string functions (`strcpy`, `strcat`, `sprintf`). This can cause a stack-based buffer overflow if an attacker provides a long file or directory name. Use safely bounded string APIs such as `snprintf`.
