Security update for the Linux Kernel (Live Patch 22 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_63 fixes several issues.
The following security issues were fixed:
- CVE-2018-5390: Prevent very expensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every incoming TCP packet which can lead to a denial of service (bsc#1102682).
- CVE-2018-10902: It was found that the raw midi kernel driver did not protect against concurrent access which lead to a double realloc (double free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(), allowing a malicious local attacker to use this for privilege escalation (bsc#1105323).
Security update for the Linux Kernel (Live Patch 25 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_82 fixes several issues.
The following security issues were fixed:
- CVE-2018-3646: Local attackers in virtualized guest systems could use speculative code patterns on hyperthreaded processors to read data present in the L1 Datacache used by other hyperthreads on the same CPU core, potentially leaking sensitive data, even from other virtual machines or the host system (bsc#1099306).
- CVE-2018-10853: A flaw was found in kvm. In which certain instructions such as sgdt/sidt call segmented_write_std didn't propagate access correctly. As such, during userspace induced exception, the guest can incor

The following security issue was fixed:
- CVE-2018-3665: System software utilizing Lazy FP state restore technique on systems using Intel Core-based microprocessors may potentially have allowed a local process to infer data from another process via a speculative execution side channel (bsc#1090338, bsc#1096740).
Security update for the Linux Kernel (Live Patch 25 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_82 fixes several issues.
The following security issues were fixed:
- CVE-2017-13166: An elevation of privilege vulnerability in the kernel v4l2 video driver was fixed. (bsc#1085447).
- CVE-2018-8897: A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Li
Security update for the Linux Kernel (Live Patch 25 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_82 fixes several issues.
The following security issues were fixed:
- CVE-2018-1000199: A bug in x86 debug register handling of ptrace() could lead to memory corruption, possibly a denial of service or privilege escalation (bsc#1090036).
- CVE-2017-0861: Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem in the Linux kernel allowed attackers to gain privileges via unspecified vectors (bsc#1088268).
Security update for the Linux Kernel (Live Patch 25 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_82 fixes several issues.
The following security issues were fixed:
- CVE-2017-13166: An elevation of privilege vulnerability was fixed in the kernel v4l2 video driver. (bsc#1085447).
- CVE-2018-1068: A flaw was found in the Linux kernels implementation of 32-bit syscall interface for bridging. This allowed a privileged user to arbitrarily write to a limited range of kernel memory (bsc#1085114).
- CVE-2018-7566: The Linux kernel had a buffer overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user (bsc#1083488).
The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.
The following security bugs were fixed:
- CVE-2017-5715: Systems with microprocessors utilizing speculative
execution and indirect branch prediction may allow unauthorized disclosure
of information to an attacker with local user access via a side-channel
analysis (bnc#1068032).
The previous fix using CPU Microcode has been complemented by building
the Linux Kernel with return trampolines aka 'retpolines'.
- CVE-2017-18079: drivers/input/serio/i8042.c allowed attackers to cause a
denial of service (NULL pointer dereference and sy
