  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 SP3 kernel was updated to 4.4.114 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-2017-15129: A use-after-free vulnerability was found in network
 namespaces code affecting the Linux kernel in the function
 get_net_ns_by_id() in net/core/net_namespace.c did not check for the
 net::count value after it has found a peer network in netns_ids idr,
 which could lead to double free and memory corruption. This
 vulnerability could allow an unprivileged local user to induce kernel
 memory corruption on the system, leading to a crash. Due to the nature
 of the flaw, privilege escalation cannot be fully ruled out, although it
 is thought to be unlikely (bnc#1074839).
- CVE-2017-17712: The raw_sendmsg() function in net/ipv4/raw.c in the
 Linux kernel has a race condition in inet->hdrincl that leads to
 uninitialized stack pointer usage, this allowed a local user to execute
 code and gain privileges (bnc#1073229).
- CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignored
 unreachable code, even though it would still be processed by JIT
 compilers. This behavior, also considered an improper branch-pruning
 logic issue, could possibly be used by local users for denial of service
 (bnc#1073928).
- CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled
 states_equal comparisons between the pointer data type and the
 UNKNOWN_VALUE data type, which allowed local users to obtain potentially
 sensitive address information, aka a 'pointer leak (bnc#1073928).
- CVE-2017-18017: The tcpmss_mangle_packet function in
 net/netfilter/xt_TCPMSS.c in the Linux kernel allowed remote attackers
 to cause a denial of service (use-after-free and memory corruption) or
 possibly have unspecified other impact by leveraging the presence of
 xt_TCPMSS in an iptables action (bnc#1074488).
- CVE-2018-5332: In the Linux kernel the rds_message_alloc_sgs() function
 did not validate a value that is used during DMA page allocation,
 leading to a heap-based out-of-bounds write (related to the
 rds_rdma_extra_size function in net/rds/rdma.c) (bnc#1075621).
- CVE-2018-5333: In the Linux kernel the rds_cmsg_atomic function in
 net/rds/rdma.c mishandled cases where page pinning fails or an invalid
 address is supplied, leading to an rds_atomic_free_op NULL pointer
 dereference (bnc#1075617).
- CVE-2018-1000004: In the Linux kernel a race condition vulnerability
 existed in the sound system, this can lead to a deadlock and denial of
 service condition ... [Please see the references for more information on the vulnerabilities]");
