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 24 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_69 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 24 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_69 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 24 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_69 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 24 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_69 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-2018-1000004: A race condition vulnerability existed in the sound system, which could lead to a deadlock and denial of service condition (bsc#1076017)
The SUSE Linux Enterprise 12 SP1 LTSS kernel was updated to receive various security and bugfixes.
This update adds mitigations for various side channel attacks against
modern CPUs that could disclose content of otherwise unreadable memory
(bnc#1068032).
- CVE-2017-5753 / 'SpectreAttack': Local attackers on systems with modern
CPUs featuring deep instruction pipelining could use attacker
controllable speculative execution over code patterns in the Linux
Kernel to leak content from otherwise not readable memory in the same
address space, allowing retrieval of passwords, cryptographic keys
and other secrets.
