CWE-228  (opens in a new tab)

How to fix?

Upgrade RHEL:7 kernel-rt-doc to version 0:3.10.0-514.rt56.420.el7 or higher.
This issue was patched in RHSA-2016:2584.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-rt-doc package and not the kernel-rt-doc package as distributed by RHEL. See How to fix? for RHEL:7 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.
