"The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple
vulnerabilities as referenced in the SUSE-SU-2023:1848-1 advisory.

  - Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized
    disclosure of information to an attacker with local user access via a side-channel analysis.
    (CVE-2017-5753)

  - A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a
    privileged local account can leak kernel stack information when issuing commands to the
    /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it
    can be further used to defeat existing kernel protection mechanisms. (CVE-2021-3923)

  - A use-after-free read flaw was found in sock_getsockopt() in net/core/sock.c due to SO_PEERCRED and
    SO_PEERGROUPS race with listen() (and connect()) in the Linux kernel. In this flaw, an attacker with a
    user privileges may crash the system or leak internal kernel information. (CVE-2021-4203)

  - In pppol2tp_create of l2tp_ppp.c, there is a possible use after free due to a race condition. 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-186777253References:
    Upstream kernel (CVE-2022-20567)

  - A NULL pointer dereference flaw was found in rawv6_push_pending_frames in net/ipv6/raw.c in the network
    subcomponent in the Linux kernel. This flaw causes the system to crash. (CVE-2023-0394)

  - A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race
    problem. This flaw leads to a denial of service issue. If patch ebda44da44f6 (net: sched: fix race
    condition in qdisc_graft()) not applied yet, then kernel could be affected. (CVE-2023-0590)

  - A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a
    type confusion in their initialization function. While it will be often correct, as tuntap devices require
    CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This
    would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing
    network filters. (CVE-2023-1076)

  - In nf_tables_updtable, if nf_tables_table_enable returns an error, nft_trans_destroy is called to free the
    transaction object. nft_trans_destroy() calls list_del(), but the transaction was never placed on a list
    -- the list head is all zeroes, this results in a NULL pointer dereference. (CVE-2023-1095)

  - Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege
    Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-
    after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this
    vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git
    commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. (CVE-2023-1281)

  - A remote denial of service vulnerability was found in the Linux kernel's TIPC kernel module. The while
    loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue.
    Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system
    to instantly spike to 100%, causing a denial of service condition. (CVE-2023-1390)

  - A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some
    uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an
    information leak. (CVE-2023-1513)

  - cbq_classify in net/sched/sch_cbq.c in the Linux kernel through 6.1.4 allows attackers to cause a denial
    of service (slab-out-of-bounds read) because of type confusion (non-negative numbers can sometimes
    indicate a TC_ACT_SHOT condition rather than valid classification results). (CVE-2023-23454)

  - atm_tc_enqueue in net/sched/sch_atm.c in the Linux kernel through 6.1.4 allows attackers to cause a denial
    of service because of type confusion (non-negative numbers can sometimes indicate a TC_ACT_SHOT condition
    rather than valid classification results). (CVE-2023-23455)

  - A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in
    the Linux Kernel. The message from user space is not checked properly before transferring into the device.
    This flaw allows a local user to crash the system or potentially cause a denial of service.
    (CVE-2023-28328)

  - hci_conn_cleanup in net/bluetooth/hci_conn.c in the Linux kernel through 6.2.9 has a use-after-free
    (observed in hci_conn_hash_flush) because of calls to hci_dev_put and hci_conn_put. There is a double free
    that may lead to privilege escalation. (CVE-2023-28464)

  - An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer
    overflow. (CVE-2023-28772)

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