Security update for the Linux Kernel (Live Patch 11 for SLE 12 SP2)
This update for the Linux Kernel 4.4.74-92_32 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)

This update for the Linux Kernel 4.4.74-92_32 fixes several issues.
The following security issues were fixed:
- CVE-2017-17712: The raw_sendmsg() function had a race condition that lead to uninitialized stack pointer usage. This allowed a local user to execute code and gain privileges (bsc#1073230).
- CVE-2017-16939: The XFRM dump policy implementation allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages (bsc#1069708).

The following security issues were fixed:
- CVE-2017-1000405: Problematic use of pmd_mkdirty() in the touch_pmd() function allowed users to overwrite read-only huge pages (e.g. the zero huge page and sealed shmem files) (bsc#1070307).
- CVE-2017-16939: The XFRM dump policy implementation in net/xfrm/xfrm_user.c kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages (bsc#1069708).
This non-security issue was fixed:

This update for the Linux Kernel 4.4.74-92_32 fixes several issues.
The following security issues were fixed:
- CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local users to gain privileges via crafted system calls that trigger mishandling of packet_fanout data structures, because of a race condition (involving fanout_add and packet_do_bind) that leads to a use-after-free, a different vulnerability than CVE-2017-6346 (bsc#1064392)
- CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay
