Security update for the Linux Kernel (Live Patch 32 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_107 fixes several issues.
The following security issues were fixed:
- CVE-2019-9213: Expand_downwards in mm/mmap.c lacked a check for the mmap minimum address, which made it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is related to a capability check for the wrong task (bsc#1128378).
- CVE-2019-7221: Fixed a user-after-free vulnerability in the KVM hypervisor related to the emulation of a preemption timer, allowing an guest user/process to crash the host kernel. (bsc#1124734).
- CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishan
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 27 for SLE 12 SP1)
This update for the Linux Kernel 3.12.74-60_64_88 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).
