CVE-2016-2053: Linux Kernel

Medium severity, CVSS 4.7. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Linux Linux Kernel: before 4.3 (fixed in 4.3)
