CVE-2025-40843 was fixed by replacing unchecked strcpy() with a bounded safe_strcpy() helper.
At ldlogger-tool-gcc.c:129 the destination passed to that helper is fullPath + 2, but the size
passed down is the full PATH_MAX. safe_strcpy() is strncpy(), which NUL-pads the
destination out to the whole n, so this site writes 4096 bytes into the 4094 that remain — a
2-byte stack overflow on every invocation, independent of the input path's length.
This issue affects CodeChecker: through 6.28.2.
