Section 3.1 says:
3.1. Encoding An integer 0 < S < L - 1 is encoded in little-endian form as a b-bit string ENC(S).
It should say:
3.1. Encoding An integer 0 <= S <= L - 1 is encoded in little-endian form as a b-bit string ENC(S).
Notes:
The range of the scalar should include the end-points: 0 and L-1.
--VERIFIER NOTE--
Verified. Section 3.1 specifies 0 < S < L - 1 (excluding both 0 and
L-1) but Section 5.1.7 verification requires 0 <= S < L (including
both endpoints). This internal inconsistency is corrected by changing
Section 3.1 to 0 <= S <= L - 1, which is mathematically equivalent
to 0 <= S < L. Security is unaffected as both formulations reject
S >= L (preventing malleability). All known implementations follow
Section 5.1.7's range. See EID 7031 (same paper - held for document
update as it adds content rather than fixing an error).

Section 3.4 says:
Compute h = H(ENC(R) || ENC(A) || M), and check the groupequation [2^c * S] B = 2^c * R + [2^c * h] A in E.
It should say:
Compute h = H(ENC(R) || ENC(A) || M), and check the groupequation [2^c * S] B = [2^c] R + [2^c * h] A in E.
Notes:
Section 2 uses a separate notation, [n]X, for point multiplication, so this operation should use the brackets.
--VERIFIER NOTE--
Verified. Section 2 defines [n]X notation for point multiplication. The term 2^c * R in Section 3.4 should use brackets [2^c] R for consistency.

Section 5.1.4 says:
However, using the formulas described in Section 3.2 of [Edwards-revisited] and in [EFD-TWISTED-DBL] saves a few smaller operations.
It should say:
However, using the formulas described in Section 3.3 of [Edwards-revisited] and in [EFD-TWISTED-DBL] saves a few smaller operations.
Notes:
In RFC 8032 Section 5.1.4, the reference to "formulas described in Section 3.2 of [Edwards-revisited]" is incorrect. Section 3.2 of [Edwards-revisited] discusses Dedicated Addition, not doubling. The doubling formulas mentioned in RFC 8032 actually appear in Section 3.3 of [Edwards-revisited], under Dedicated Doubling.
--VERIFIER NOTE--
Verified. Section 5.1.4 discusses doubling formulas from Edwards-revisited. Section 3.2 of that paper covers addition formulas; Section 3.3 covers doubling formulas. The reference should be Section 3.3. Confirmed via Explicit Formulas Database at hyperelliptic.org.

Notes:
original document expression is ' 0 <= s < L', but it must be '0 <= S < L'. upper/lower case problem.

Section 5.1.7 says:
Decode the first half as a point R, and the second half as an integer S, in the range 0 <= s < L. Decode the public key A as point A'. If any of the decodings fail (including S being out of range), the signature is invalid. 2. Compute SHA512(dom2(F, C) || R || A || PH(M)), and interpret the 64-octet digest as a little-endian integer k. 3. Check the group equation [8][S]B = [8]R + [8][k]A'. It's sufficient, but not required, to instead check [S]B = R + [k]A'.
It should say:

It's sufficient, but not required, to instead check [S]B = R' + [k]A'.
Notes:
1) public key R' and its encoding R are confused
2) s changed to S (this errata has been reported already)
Held for Document Update: Errata 6306 suggests clarifying variable names in Section 5.1.7's decoding components to reduce ambiguity in signature verification processes. The adjustments are editorial but help improve implementation clarity, particularly for complex protocols that rely on accurate component identification. Suitable for future document updates. - CFRG co-chair

Notes:
Some of these vectors are not expected to validate. See https://github.com/novifinancial/ed25519-speccheck and Taming the many EdDSAs by Konstantinos Chalkias, François Garillot, and Valeria Nikolaenko https://eprint.iacr.org/2020/1244
--VERIFIER NOTE--
Held for document update. This erratum proposes adding 12 test vectors from "Taming the many EdDSAs" (eprint 2020/1244), not correcting an error. The existing vectors are correct. Adding edge case vectors would implicitly impose constraints on behaviors RFC 8032 intentionally left unspecified (small-order points, cofactor verification, canonical encoding). Appropriate for RFC 8032-bis with corresponding normative clarifications. See EID 5968 (scalar range from same paper - verified as it fixes actual inconsistency).

Section .1 says:
An element (x,y) of E is encoded as a b-bit string called ENC(x,y), which is the (b-1)-bit encoding of y concatenated with one bit that is 1 if x is negative and 0 if x is not negative.
It should say:
An element (x,y) of E is encoded as a b-bit string called ENC(x,y), which is the (b-1)-bit encoding of y concatenated with the least significant bit of x.
Notes:
Section 3.1 is not coherent with encodings described for Ed25519 (5.1.2) and Ed448 (5.2.2)
