How to fix?

There is no fixed version for RHEL:10 realtime-kernel.

NVD Description

Note: Versions mentioned in the description apply only to the upstream realtime-kernel package and not the realtime-kernel package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c.
