NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-debug package and not the kernel-rt-debug package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
