CVE-2026-22184 is a global buffer overflow in the standalone untgz demonstration utility distributed under zlib's contrib/untgz directory. In affected zlib versions through 1.3.1.2, TGZfname() uses an unbounded strcpy() operation to copy an archive name into a fixed-size 1024-byte static global buffer. An excessively long archive-name command-line argument causes an out-of-bounds write. The vulnerability is limited to untgz and does not affect the core zlib compression library.
