The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1739 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: Integer overflow in Intel(R) Graphics Drivers (CVE-2020-12362)

    * kernel: use-after-free caused by a malicious USB device in the drivers/usb/misc/adutux.c driver     (CVE-2019-19523)

    * kernel: use-after-free bug caused by a malicious USB device in the drivers/usb/misc/iowarrior.c driver     (CVE-2019-19528)

    * kernel: possible out of bounds write in kbd_keycode of keyboard.c (CVE-2020-0431)

    * kernel: DoS by corrupting mountpoint reference counter (CVE-2020-12114)

    * kernel: use-after-free in usb_sg_cancel function in drivers/usb/core/message.c (CVE-2020-12464)

    * kernel: buffer uses out of index in ext3/4 filesystem (CVE-2020-14314)

    * kernel: Use After Free vulnerability in cgroup BPF component (CVE-2020-14356)

    * kernel: NULL pointer dereference in serial8250_isa_init_ports function in     drivers/tty/serial/8250/8250_core.c (CVE-2020-15437)

    * kernel: umask not applied on filesystem without ACL support (CVE-2020-24394)

    * kernel: TOCTOU mismatch in the NFS client code (CVE-2020-25212)

    * kernel: incomplete permission checking for access to rbd devices (CVE-2020-25284)

    * kernel: race condition between hugetlb sysctl handlers in mm/hugetlb.c (CVE-2020-25285)

    * kernel: improper input validation in ppp_cp_parse_cr function leads to memory corruption and read     overflow (CVE-2020-25643)

    * kernel: perf_event_parse_addr_filter memory (CVE-2020-25704)

    * kernel: use-after-free in kernel midi subsystem (CVE-2020-27786)

    * kernel: child process is able to access parent mm through hfi dev file handle (CVE-2020-27835)

    * kernel: slab-out-of-bounds read in fbcon (CVE-2020-28974)

    * kernel: fork: fix copy_process(CLONE_PARENT) race with the exiting ->real_parent (CVE-2020-35508)

    * kernel: use after free in tun_get_user of tun.c could lead to local escalation of privilege     (CVE-2021-0342)

    * kernel: NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs in     drivers/media/usb/gspca/ov519.c (CVE-2020-11608)
