Doc Text:
A flaw was found in the liboqs library. A correctness error has been identified in the reference implementation of the HQC key encapsulation mechanism. Due to an indexing error, part of the secret key is incorrectly treated as non-secret data. This issue results in an incorrect shared secret value being returned when the decapsulation function is called with a malformed ciphertext.

Description OSIDB Bzimport 2024-12-06 17:02:25 UTC 
liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. A correctness error has been identified in the reference implementation of the HQC key encapsulation mechanism. Due to an indexing error, part of the secret key is incorrectly treated as non-secret data. This results in an incorrect shared secret value being returned when the decapsulation function is called with a malformed ciphertext. This vulnerability is fixed in 0.12.0.
Comment 2 Dmitry Belyavskiy 2024-12-09 09:02:36 UTC 
We don't build HQC in our build of liboqs.
