How many bits in decrypted at receiver could be corrupted

Question

Problem

With the ECB mode, if there is a one-bit error in a block of the transmitted ciphertext, only the corresponding plaintext block is affected in the decryption. However, in the CBC mode, this error propagates.

1) How many bits in the decrypted P₁ and P₂ at the receiver could be corrupted, respectively, assuming AES is used as the block cipher?

2) Are any decrypted blocks beyond P₂ affected?

3) Suppose that there is a one-bit error in the source version of P₁. Through how many ciphertext blocks is this error propagated? What is the effect at the receiver?
