Security update for Linux Kernel Live Patch 2 for SLE 12 SP2
This update for the Linux Kernel 4.4.21-84 fixes several issues.
The following security bugs were fixed:
- CVE-2017-7533: A bug in inotify code allowed local users to escalate privilege (bsc#1050751).
- CVE-2017-8797: The NFSv4 server in the Linux kernel did not properly validate the layout type when processing the NFSv4 pNFS GETDEVICEINFO or LAYOUTGET operand in a UDP packet from a remote attacker. This type value is uninitialized upon encountering certain error conditions. This value is used as an array index for dereferencing, which leads to an OOPS and eventually a DoS of knfsd and a soft-lockup of the whole system (bsc#1046202)

The following security bugs were fixed:
- CVE-2017-1000364: An issue was discovered in the size of the stack guard page on Linux, specifically a 4k stack guard page is not sufficiently large and can be 'jumped' over (the stack guard page is bypassed) (bsc#1039496).
Security update for Linux Kernel Live Patch 2 for SLE 12 SP2
This update for the Linux Kernel 4.4.21-84 fixes several issues.
The following security bugs were fixed:
- CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bsc#1030575, bsc#1031660).
- CVE-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bou
Security update for Linux Kernel Live Patch 2 for SLE 12 SP2
This update for the Linux Kernel 4.4.21-84 fixes one issue.
The following security bugs were fixed:
- CVE-2017-7184: The XFRM processsing in the Linux kernel 16.10 allowed local users to obtain root privileges or cause a denial of service (heap-based out-of-bounds access) via an integer overflow, as demonstrated during a Pwn2Own competition at CanSecWest 2017 (bsc#1030575).

The following security bug was fixed:
- CVE-2017-5970: The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a denial of service (system crash) via (1) an application that made crafted system calls or possibly (2) IPv4 traffic with invalid IP options (bsc#1025013).

The following security bugs were fixed:
- CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576 (bsc#1019079).
- CVE-2016-9794: Race condition in the snd_pcm_period_elapsed function in sound/core
