The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:7444 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):

    * off-path attacker may inject data or terminate victim's TCP session (CVE-2020-36516)

    * Race condition in VT_RESIZEX ioctl when vc_cons[i].d is already NULL leading to NULL pointer dereference     (CVE-2020-36558)

    * use-after-free vulnerability in function sco_sock_sendmsg() (CVE-2021-3640)

    * Memory leak for large arguments in video_usercopy function in drivers/media/v4l2-core/v4l2-ioctl.c     (CVE-2021-30002)

    * smb2_ioctl_query_info NULL Pointer Dereference (CVE-2022-0168)

    * NULL pointer dereference in udf_expand_file_adinicbdue() during writeback (CVE-2022-0617)

    * swiotlb information leak with DMA_FROM_DEVICE (CVE-2022-0854)

    * Uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM (CVE-2022-1016)

    * Race condition in snd_pcm_hw_free leading to use-after-free (CVE-2022-1048)

    * use-after-free in tc_new_tfilter() in net/sched/cls_api.c (CVE-2022-1055)

    * use-after-free and memory errors in ext4 when mounting and operating on a corrupted image     (CVE-2022-1184)

    * NULL pointer dereference in x86_emulate_insn may lead to DoS (CVE-2022-1852)

    * buffer overflow in nft_set_desc_concat_parse() (CVE-2022-2078)

    * nf_tables cross-table potential use-after-free may lead to local privilege escalation (CVE-2022-2586)

    * openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-2022-2639)

    * use-after-free when psi trigger is destroyed while being polled (CVE-2022-2938)

    * net/packet: slab-out-of-bounds access in packet_recvmsg() (CVE-2022-20368)

    * possible to use the debugger to write zero into a location of choice (CVE-2022-21499)

    * Post-barrier Return Stack Buffer Predictions (CVE-2022-26373)

    * Memory leak in drivers/hid/hid-elo.c (CVE-2022-27950)

    * Double free in ems_usb_start_xmit in drivers/net/can/usb/ems_usb.c (CVE-2022-28390)

    * Use after free in SUNRPC subsystem (CVE-2022-28893)

    * use-after-free due to improper update of reference count in net/sched/cls_u32.c (CVE-2022-29581)

    * DoS in nfqnl_mangle in net/netfilter/nfnetlink_queue.c (CVE-2022-36946)

    * nfs_atomic_open() returns uninitialized data instead of ENOTDIR (CVE-2022-24448)
