A buffer over-read flaw was found in RH kernel versions before 5.0 in
crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic
algorithm’s module, authenc. When a payload longer than 4 bytes, and is not
following 4-byte alignment boundary guidelines, it causes a buffer
over-read threat, leading to a system crash. This flaw allows a local
attacker with user privileges to cause a denial of service.
