    It was discovered that a use-after-free vulnerability existed in the
    Appletalk implementation in the Linux kernel if an error occurs during
    initialization. A local attacker could use this to cause a denial of
    service (system crash). (CVE-2019-15292)
    
    It was discovered that the Empia EM28xx DVB USB device driver
    implementation in the Linux kernel contained a use-after-free
    vulnerability when disconnecting the device. An attacker could use
    this to cause a denial of service (system crash). (CVE-2019-2024)
    
    It was discovered that the USB video device class implementation in
    the Linux kernel did not properly validate control bits, resulting in
    an out of bounds buffer read. A local attacker could use this to
    possibly expose sensitive information (kernel memory). (CVE-2019-2101)
    
    It was discovered that the Marvell Wireless LAN device driver in the
    Linux kernel did not properly validate the BSS descriptor. A local
    attacker could possibly use this to cause a denial of service (system
    crash) or possibly execute arbitrary code. (CVE-2019-3846)
    
    Jason Wang discovered that an infinite loop vulnerability existed in
    the virtio net driver in the Linux kernel. A local attacker in a guest
    VM could possibly use this to cause a denial of service in the host
    system. (CVE-2019-3900)
    
    Daniele Antonioli, Nils Ole Tippenhauer, and Kasper B. Rasmussen
    discovered that the Bluetooth protocol BR/EDR specification did not
    properly require sufficiently strong encryption key lengths. A
    physicall proximate attacker could use this to expose sensitive
    information. (CVE-2019-9506)
    
    It was discovered that the Appletalk IP encapsulation driver in the
    Linux kernel did not properly prevent kernel addresses from being
    copied to user space. A local attacker with the CAP_NET_ADMIN
    capability could use this to expose sensitive information.
    (CVE-2018-20511)

    "The SUSE Linux Enterprise 12 SP4 kernel was updated to receive various
    security and bugfixes.
    
    The following security bugs were fixed :
    
    CVE-2018-20669: Missing access control checks in ioctl of gpu/drm/i915
    driver were fixed which might have lead to information leaks.
    (bnc#1122971).
    
    CVE-2019-3459, CVE-2019-3460: The Bluetooth stack suffered from two
    remote information leak vulnerabilities in the code that handles
    incoming L2cap configuration packets (bsc#1120758).
    
    CVE-2019-3819: A flaw was found in the function
    hid_debug_events_read() in drivers/hid/hid-debug.c file which may
    enter an infinite loop with certain parameters passed from a
    userspace. A local privileged user ('root') can cause a system lock up
    and a denial of service. (bnc#1123161).
    
    CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c
    mishandled reference counting because of a race condition, leading to
    a use-after-free (bnc#1124728 ).
    
    CVE-2019-7221: Fixed a use-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#1124732).
    
    CVE-2019-7222: Fixed an information leakage in the KVM hypervisor
    related to handling page fault exceptions, which allowed a guest
    user/process to use this flaw to leak the host's stack memory contents
    to a guest (bsc#1124735).
    
    CVE-2019-7308: kernel/bpf/verifier.c performed undesirable
    out-of-bounds speculation on pointer arithmetic in various cases,
    including cases of different branches with different state or limits
    to sanitize, leading to side-channel attacks (bnc#1124055).
    
    CVE-2019-8912: af_alg_release() in crypto/af_alg.c neglects to set a
    NULL value for a certain structure member, which leads to a
    use-after-free in sockfs_setattr (bnc#1125907).
    
    CVE-2019-8980: A memory leak in the kernel_read_file function in
    fs/exec.c allowed attackers to cause a denial of service (memory
    consumption) by triggering vfs_read failures (bnc#1126209).
    
    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 (bnc#1128166).
    
    CVE-2019-2024: A use-after-free when disconnecting a source was fixed
    which could lead to crashes. bnc#1129179).
    
    The update package also includes non-security fixes. See advisory for
    details.

    description block directly from the SUSE security advisory. Tenable

    descriptionThe SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various security and bugfixes. The following security bugs were fixed : CVE-2019-2024: A use-after-free when disconnecting a source was fixed which could lead to crashes. bnc#1129179). 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 (bnc#1128166). CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. (bnc#1107829). CVE-2019-7221: The KVM implementation in the Linux kernel had a Use-after-Free (bnc#1124732). CVE-2019-7222: The KVM implementation in the Linux kernel had an Information Leak (bnc#1124735). CVE-2019-6974: kvm_ioctl_create_device in virt/kvm/kvm_main.c mishandled reference counting because of a race condition, which led to a use-after-free (bnc#1124728). The update package also includes non-security fixes. See advisory for details. Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory.

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. This updated advisory text adds a note about the need to install new binary packages. CVE-2018-5995 ADLab of VenusTech discovered that the kernel logged the virtual addresses assigned to per-CPU data, which could make it easier to exploit other vulnerabilities. CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, CVE-2019-11091 Multiple researchers have discovered vulnerabilities in the way that Intel processor designs implement speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system, or across guest/host boundaries to read host memory. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/m ds.html for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. An updated intel-microcode package (only available in Debian non-free) was provided via DLA-1789-1. The updated CPU microcode may also be available as part of a system firmware (
