The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:8267 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

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

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

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

    * concurrency use-after-free between drm_setmaster_ioctl and drm_mode_getresources (CVE-2022-1280)

    * kernel info leak issue in pfkey_register (CVE-2022-1353)

    * use-after-free in ath9k_htc_probe_device() could cause an escalation of privileges (CVE-2022-1679)

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

    * fanotify misuses fd_install() which could lead to use-after-free (CVE-2022-1998)

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

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

    * slab-out-of-bounds access in packet_recvmsg() (CVE-2022-20368)

    * incomplete clean-up of multi-core shared buffers (aka SBDR) (CVE-2022-21123)

    * incomplete clean-up of microarchitectural fill buffers (aka SBDS) (CVE-2022-21125)

    * incomplete clean-up in specific special register write operations (aka DRPW) (CVE-2022-21166)

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

    * AMD: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-23816,     CVE-2022-29900)

    * AMD: Branch Type Confusion (non-retbleed) (CVE-2022-23825)

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

    * 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)

    * Intel: RetBleed Arbitrary Speculative Code Execution with Return Instructions (CVE-2022-29901)

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

    * nf_tables disallow binding to already bound chain (CVE-2022-39190)

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

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Dm-verity is used for extending root-of-trust to root filesystems.
LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates. We recommend upgrading past commit 4caae58406f8ceb741603eee460d79bacca9b1b5
