Security update for the Linux Kernel (Live Patch 17 for SLE 12 SP2)

This update for the Linux Kernel 4.4.103-92_56 fixes several issues.

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).

Non security issue fixed:

  • btrfs: account for pinned bytes in should_alloc_chunk (bsc#1077268)
