- [Denial of service with specially crafted key file]
+ 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.
