"The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as
referenced in the SUSE-SU-2023:1609-1 advisory.

  - A vulnerability was found in Linux Kernel. It has been classified as problematic. Affected is an unknown
    function of the file mm/memory.c of the component Driver Handler. The manipulation leads to use after
    free. It is possible to launch the attack remotely. It is recommended to apply a patch to fix this issue.
    The identifier of this vulnerability is VDB-211020. (CVE-2022-3523)

  - A NULL pointer dereference vulnerability was found in vmwgfx driver in drivers/gpu/vmxgfx/vmxgfx_execbuf.c
    in GPU component of Linux kernel with device file '/dev/dri/renderD128 (or Dxxx)'. This flaw allows a
    local attacker with a user account on the system to gain privilege, causing a denial of service(DoS).
    (CVE-2022-38096)

  - There is a use-after-free vulnerability in the Linux Kernel which can be exploited to achieve local
    privilege escalation. To reach the vulnerability kernel configuration flag CONFIG_TLS or
    CONFIG_XFRM_ESPINTCP has to be configured, but the operation does not require any privilege. There is a
    use-after-free bug of icsk_ulp_data of a struct inet_connection_sock. When CONFIG_TLS is enabled, user can
    install a tls context (struct tls_context) on a connected tcp socket. The context is not cleared if this
    socket is disconnected and reused as a listener. If a new socket is created from the listener, the context
    is inherited and vulnerable. The setsockopt TCP_ULP operation does not require any privilege. We recommend
    upgrading past commit 2c02d41d71f90a5168391b6a5f2954112ba2307c (CVE-2023-0461)

  - A flaw possibility of memory leak in the Linux kernel cpu_entry_area mapping of X86 CPU data to memory was
    found in the way user can guess location of exception stack(s) or other important data. A local user could
    use this flaw to get access to some important data with expected location in memory. (CVE-2023-0597)

  - A flaw was found in the Linux Kernel. The tls_is_tx_ready() incorrectly checks for list emptiness,
    potentially accessing a type confused entry to the list_head, leaking the last byte of the confused field
    that overlaps with rec->tx_ready. (CVE-2023-1075)

  - 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)

  - A flaw was found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The
    rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user
    can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info`
    actually points to something else that is potentially controlled by local user. It is known how to trigger
    this, which causes an out of bounds access, and a lock corruption. (CVE-2023-1078)

  - 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)

  - A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the
    way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate
    their privileges on the system. (CVE-2023-1118)

  - In the Linux kernel before 5.17, an error path in dwc3_qcom_acpi_register_core in
    drivers/usb/dwc3/dwc3-qcom.c lacks certain platform_device_put and kfree calls. (CVE-2023-22995)

  - In the Linux kernel before 6.0.3, drivers/gpu/drm/virtio/virtgpu_object.c misinterprets the
    drm_gem_shmem_get_sg_table return value (expects it to be NULL in the error case, whereas it is actually
    an error pointer). (CVE-2023-22998)

  - In the Linux kernel before 5.17, drivers/phy/tegra/xusb.c mishandles the tegra_xusb_find_port_node return
    value. Callers expect NULL in the error case, but an error pointer is used. (CVE-2023-23000)

  - In the Linux kernel before 5.19, drivers/gpu/drm/arm/malidp_planes.c misinterprets the get_sg_table return
    value (expects it to be NULL in the error case, whereas it is actually an error pointer). (CVE-2023-23004)

  - In rndis_query_oid in drivers/net/wireless/rndis_wlan.c in the Linux kernel through 6.1.5, there is an
    integer overflow in an addition. (CVE-2023-23559)

  - The Linux kernel through 6.1.9 has a Use-After-Free in bigben_remove in drivers/hid/hid-bigbenff.c via a
    crafted USB device because the LED controllers remain registered for too long. (CVE-2023-25012)

  - In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure
    (for registering the sysctl table under a new location) during the renaming of a device. (CVE-2023-26545)

  - 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)
