The following security issue was fixed:

  • CVE-2017-18075: crypto/pcrypt.c in the Linux kernel mishandled freeing instances, allowing a local user able to access the AF_ALG-based AEAD interface (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt (CONFIG_CRYPTO_PCRYPT) to cause a denial of service (kfree of an incorrect pointer) or possibly have unspecified other impact by executing a crafted sequence of system calls (bsc#1077404).
