"The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2021:3935-1 advisory.

  - kernel/bpf/verifier.c in the Linux kernel through 4.14.8 ignores 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. (CVE-2017-17862)

  - kernel/bpf/verifier.c in the Linux kernel through 4.14.8 mishandles states_equal comparisons between the
    pointer data type and the UNKNOWN_VALUE data type, which allows local users to obtain potentially
    sensitive address information, aka a pointer leak. (CVE-2017-17864)

  - The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create
    files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and
    is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a
    plain file whose group ownership is that group. The intended behavior was that the non-member can trigger
    creation of a directory (but not a plain file) whose group ownership is that group. The non-member can
    escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

  - A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts
    when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error while
    processing posted interrupt address, it unmaps the 'pi_desc_page' without resetting 'pi_desc' descriptor
    address, which is later used in pi_test_and_clear_on(). A guest user/process could use this flaw to crash
    the host kernel resulting in DoS or potentially gain privileged access to a system. Kernel versions before
    4.14.91 and before 4.19.13 are vulnerable. (CVE-2018-16882)

  - In l2tp_session_delete and related functions of l2tp_core.c, there is possible memory corruption due to a
    use after free. This could lead to local escalation of privilege with System execution privileges needed.
    User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-152735806 (CVE-2020-0429)

  - An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through 5.6.10.
    Attackers may trigger a sync of excessive duration via an XFS v5 image with crafted metadata, aka
    CID-d0c7feaf8767. (CVE-2020-12655)

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection
    tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote
    user to crash the system, causing a denial of service. The highest threat from this vulnerability is to
    confidentiality, integrity, as well as system availability. (CVE-2020-14305)

  - u'Specifically timed and handcrafted traffic can cause internal errors in a WLAN device that lead to
    improper layer 2 Wi-Fi encryption with a consequent possibility of information disclosure over the air for
    a discrete set of traffic' in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon
    Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon
    Wearables, Snapdragon Wired Infrastructure and Networking in APQ8053, IPQ4019, IPQ8064, MSM8909W,
    MSM8996AU, QCA9531, QCN5502, QCS405, SDX20, SM6150, SM7150 (CVE-2020-3702)

  - IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors could allow a local user to obtain sensitive
    information from the data in the L1 cache under extenuating circumstances. IBM X-Force ID: 189296.
    (CVE-2020-4788)

  - A flaw was found in the way memory resources were freed in the unix_stream_recvmsg function in the Linux
    kernel when a signal was pending. This flaw allows an unprivileged local user to crash the system by
    exhausting available memory. The highest threat from this vulnerability is to system availability.
    (CVE-2021-20265)

  - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux
    kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an
    off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this
    vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source
    port randomization are indirectly affected as well. (CVE-2021-20322)

  - An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-
    device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with
    special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or
    a leak of internal kernel information. The highest threat from this vulnerability is to system
    availability. (CVE-2021-31916)

  - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because
    the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads
    to writing an arbitrary value. (CVE-2021-33033)

  - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from
    kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects
    the possibility of uninitialized memory locations on the BPF stack. (CVE-2021-34556)

  - A flaw was found in the Linux kernel's CAPI over Bluetooth connection code. An attacker with a local
    account can escalate privileges when CAPI (ISDN) hardware connection fails. (CVE-2021-34981)

  - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from
    kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store
    operation does not necessarily occur before a store operation that has an attacker-controlled value.
    (CVE-2021-35477)

  - A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the
    way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del()
    together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A
    privileged local user could use this flaw to crash the system or escalate their privileges on the system.
    (CVE-2021-3640)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when
    processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested
    guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to
    enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest
    would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak
    of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to
    5.14-rc7. (CVE-2021-3653)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on
    inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - A NULL pointer dereference flaw was found in the Linux kernel's IEEE 802.15.4 wireless networking
    subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the
    system. The highest threat from this vulnerability is to system availability. (CVE-2021-3659)

  - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was
    found in the way user uses trace ring buffer in a specific way. Only privileged local users (with
    CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
    (CVE-2021-3679)

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking
    subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat
    from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev
    without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
    (CVE-2021-37159)

  - A flaw was found in the Linux kernel's OverlayFS subsystem in the way the user mounts the TmpFS filesystem
    with OverlayFS. This flaw allows a local user to gain access to hidden files that should not be
    accessible. (CVE-2021-3732)

  - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to
    the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the
    system or escalate their privileges. The highest threat from this vulnerability is to confidentiality,
    integrity, as well as system availability. (CVE-2021-3752)

  - A race problem was seen in the vt_k_ioctl in drivers/tty/vt/vt_ioctl.c in the Linux kernel, which may
    cause an out of bounds read in vt as the write access to vc_mode is not protected by lock-in vt_ioctl
    (KDSETMDE). The highest threat from this vulnerability is to data confidentiality. (CVE-2021-3753)

  - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest
    OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

  - A flaw was found in the Linux kernel. A use-after-free vulnerability in the NFC stack can lead to a threat
    to confidentiality, integrity, and system availability. (CVE-2021-3760)

  - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP
    association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and
    the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

  - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss
    can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the
    length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

  - arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access
    permissions of a shadow page, leading to a missing guest protection page fault. (CVE-2021-38198)

  - drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to
    cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain
    situations. (CVE-2021-38204)

  - A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in
    the Linux kernel through 5.13.13. (CVE-2021-40490)

  - The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab
    out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
    (CVE-2021-42008)

  - A heap-based buffer overflow flaw was found in the Linux kernel FireDTV media card driver, where the user
    calls the CA_SEND_MSG ioctl. This flaw allows a local user of the host machine to crash the system or
    escalate privileges on the system. The highest threat from this vulnerability is to confidentiality,
    integrity, as well as system availability. (CVE-2021-42739)

  - An issue was discovered in the Linux kernel before 5.14.15. There is an array-index-out-of-bounds flaw in
    the detach_capi_ctr function in drivers/isdn/capi/kcapi.c. (CVE-2021-43389)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
