NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-firmware package and not the kernel-uek-firmware package as distributed by Oracle. See How to fix? for Oracle:6 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.
