CVE-2015-3331

Description

The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket.
