If your plaintext always happens to be n ∗ 16 + 15 bytes in size then your padding would consist of a single byte. A single byte is never enough to guarantee integrity of the plaintext. Padding isn't a checksum.

What is the difference between PKCS#5 padding and PKCS#7 padding

WebApr 13, 2024 · PKCS5 padding is a narrowly defined subset of PKCS7 as per its specification. PKCS7 padding is identical to PKCS5 when applied to an 8-byte block only. The PKCS5 specification is actually defined only for DES, not 64-bit block ciphers in general.
