Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a     network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,     CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary     can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other     clients even though the sender has not yet successfully authenticated to the AP. This might be abused in     projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier     to exploit other vulnerabilities in connected clients. (CVE-2020-26139)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and     WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to     inject arbitrary data frames independent of the network configuration. (CVE-2020-26140)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation     does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can     abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-     confidentiality protocol. (CVE-2020-26141)

  - An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat     fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets,     independent of the network configuration. (CVE-2020-26142)

  - An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and     WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can     abuse this to inject arbitrary data frames independent of the network configuration. (CVE-2020-26143)

  - A flaw was found in the Linux kernel, where the WiFi implementations accept plaintext A-MSDU frames as     long as the first 8 bytes correspond to a valid RFC1042 (ex., LLC/SNAP) header for EAPOL. The highest     threat from this vulnerability is to integrity. (CVE-2020-26144)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process     them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26145)

  - A vulnerability was found in Linux kernel, where the WiFi implementation reassemble fragments with non-     consecutive packet numbers. An adversary can abuse this to exfiltrate selected fragments. This     vulnerability is exploitable when another device sends fragmented frames and the WEP, CCMP, or GCMP data-     confidentiality protocol is used. Note that WEP is vulnerable to this attack by design. (CVE-2020-26146)

  - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble     fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject     packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)

An update of the linux package has been released.

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:3876-1 advisory.

  - The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create     files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and     is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a     plain file whose group ownership is that group. The intended behavior was that the non-member can trigger     creation of a directory (but not a plain file) whose group ownership is that group. The non-member can     escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

  - In bpf_skb_change_head of filter.c, there is a possible out of bounds read due to a use after free. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-154177719References:
    Upstream kernel (CVE-2021-0941)

  - An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass     RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users     with the ability to start and control a VM to read/write random pages of memory and can result in local     privilege escalation. (CVE-2021-22543)

  - An out-of-bounds (OOB) memory write flaw was found in list_devices in drivers/md/dm-ioctl.c in the Multi-     device driver module in the Linux kernel before 5.12. A bound check failure allows an attacker with     special user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory leading to a system crash or     a leak of internal kernel information. The highest threat from this vulnerability is to system     availability. (CVE-2021-31916)

  - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because     the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads     to writing an arbitrary value. (CVE-2021-33033)

  - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)

  - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from     kernel memory via a Speculative Store Bypass side-channel attack because the protection mechanism neglects     the possibility of uninitialized memory locations on the BPF stack. (CVE-2021-34556)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2021-42739. Reason: This candidate is a     reservation duplicate of CVE-2021-42739. Notes: All CVE users should reference CVE-2021-42739 instead of     this candidate. All references and descriptions in this candidate have been removed to prevent accidental     usage. (CVE-2021-3542)

  - In the Linux kernel through 5.13.7, an unprivileged BPF program can obtain sensitive information from     kernel memory via a Speculative Store Bypass side-channel attack because a certain preempting store     operation does not necessarily occur before a store operation that has an attacker-controlled value.
    (CVE-2021-35477)

  - A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when     processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested     guest (L2). Due to improper validation of the int_ctl field, this issue could allow a malicious L1 to     enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest     would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak     of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to     5.14-rc7. (CVE-2021-3653)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on     inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - kernel: SVM nested virtualization issue in KVM (VMLOAD/VMSAVE) (CVE-2021-3656)

  - kernel: NULL pointer dereference in llsec_key_alloc() in net/mac802154/llsec.c (CVE-2021-3659)

  - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was     found in the way user uses trace ring buffer in a specific way. Only privileged local users (with     CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
    (CVE-2021-3679)

  - kernel: use-after-free in route4_change() in net/sched/cls_route.c (CVE-2021-3715)

  - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev     without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
    (CVE-2021-37159)

  - kernel: overlayfs: Mounting overlayfs inside an unprivileged user namespace can reveal files     (CVE-2021-3732)

  - ccp - fix resource leaks in ccp_run_aes_gcm_cmd() [fedora-all] (CVE-2021-3744)

  - A flaw was found in the Linux kernel. When reusing a socket with an attached dccps_hc_tx_ccid as a     listener, the socket will be used after being released leading to denial of service (DoS) or a potential     code execution. The highest threat from this vulnerability is to data confidentiality and integrity as     well as system availability. (CVE-2020-16119) (CVE-2021-3753)

  - arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest     OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e. (CVE-2021-37576)

  - A flaw was found in the Linux kernel. A corrupted timer tree caused the task wakeup to be missing in the     timerqueue_add function in lib/timerqueue.c. This flaw allows a local attacker with special user     privileges to cause a denial of service, slowing and eventually stopping the system while running OSP. The     highest threat from this vulnerability is system availability. (CVE-2021-20317) (CVE-2021-3764)

  - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

  - arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access     permissions of a shadow page, leading to a missing guest protection page fault. (CVE-2021-38198)

  - drivers/usb/host/max3421-hcd.c in the Linux kernel before 5.13.6 allows physically proximate attackers to     cause a denial of service (use-after-free and panic) by removing a MAX-3421 USB device in certain     situations. (CVE-2021-38204)

  - A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in     the Linux kernel through 5.13.13. (CVE-2021-40490)

  - prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel through 5.14.9 allows     unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds     write. (CVE-2021-41864)

  - The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab     out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.
    (CVE-2021-42008)

  - An issue was discovered in aspeed_lpc_ctrl_mmap in drivers/soc/aspeed/aspeed-lpc-ctrl.c in the Linux     kernel before 5.14.6. Local attackers able to access the Aspeed LPC control interface could overwrite     memory in the kernel and potentially execute privileges, aka CID-b49a0e69a7b1. This occurs because a     certain comparison uses values that are not memory sizes. (CVE-2021-42252)

  - The firewire subsystem in the Linux kernel through 5.14.13 has a buffer overflow related to     drivers/media/firewire/firedtv-avc.c and drivers/media/firewire/firedtv-ci.c, because avc_ca_pmt     mishandles bounds checking. (CVE-2021-42739)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-347.el9 build changelog.

  - A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends     a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
    This flaw allows a remote user to crash the system or possibly escalate their privileges if they have     access to the TIPC network. (CVE-2022-0435)

  - An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-     Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of     user-supplied sizes for the MSG_CRYPTO message type. (CVE-2021-43267)

  - A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could     happen if removing device (that is not common to remove video card physically without power-off, but same     happens if unbind the driver). (CVE-2020-27820)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A flaw in the processing of received ICMP errors (ICMP fragment needed and ICMP redirect) in the Linux     kernel functionality was found to allow the ability to quickly scan open UDP ports. This flaw allows an     off-path remote user to effectively bypass the source port UDP randomization. The highest threat from this     vulnerability is to confidentiality and possibly integrity, because software that relies on UDP source     port randomization are indirectly affected as well. (CVE-2021-20322)
