The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1070 advisory.

    The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with     extremely high determinism requirements.

    Security Fix(es):

    * kernel: out of bound read in DVB connexant driver. (CVE-2015-9289)

    * kernel: Missing permissions check for request_key() destination allows local attackers to add keys to     keyring without Write permission (CVE-2017-17807)

    * kernel: denial of service via ioctl call in network tun handling (CVE-2018-7191)

    * kernel: usb: missing size check in the __usb_get_extra_descriptor() leading to DoS (CVE-2018-20169)

    * kernel: perf_event_open() and execve() race in setuid programs allows a data leak (CVE-2019-3901)

    * kernel: brcmfmac frame validation bypass (CVE-2019-9503)

    * kernel: null-pointer dereference in hci_uart_set_flow_control (CVE-2019-10207)

    * kernel: sensitive information disclosure from kernel stack memory via HIDPCONNADD command     (CVE-2019-11884)

    * kernel: unchecked kstrdup of fwstr in drm_load_edid_firmware leads to denial of service (CVE-2019-12382)

    * kernel: use-after-free in arch/x86/lib/insn-eval.c (CVE-2019-13233)

    * kernel: integer overflow and OOB read in drivers/block/floppy.c (CVE-2019-14283)

    * kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service     (CVE-2019-15916)

    * kernel: buffer-overflow hardening in WiFi beacon validation code. (CVE-2019-16746)

    * kernel: oob memory read in hso_probe in drivers/net/usb/hso.c (CVE-2018-19985)

    * Kernel: net: weak IP ID generation leads to remote device tracking (CVE-2019-10638)

    * Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR     (CVE-2019-10639)

    * kernel: ASLR bypass for setuid binaries due to late install_exec_creds() (CVE-2019-11190)
