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

    The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in     drivers/net/ethernet/qualcomm/emac/emac.c if a physically proximate attacker unplugs an emac based     device.(CVE-2023-33203)

    In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled.(CVE-2023-32233)

    A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the     extra inode size for extended attributes. This flaw could allow a privileged local user to cause a system     crash or other undefined behaviors.(CVE-2023-2513)

    ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2023-33203. Reason: This candidate is a     reservation duplicate of CVE-2023-33203. Notes: All CVE users should reference CVE-2023-33203 instead of     this candidate. All references and descriptions in this candidate have been removed to prevent accidental     usage.(CVE-2023-2483)

    A speculative pointer dereference problem exists in the Linux Kernel on the do_prlimit() function. The     resource argument value is controlled and is used in pointer arithmetic for the 'rlim' variable and can be     used to leak the contents. We recommend upgrading past version 6.1.8 or     commit739790605705ddcf18f21782b9c99ad7d53a8c11(CVE-2023-0458)

    An out-of-bounds memory access flaw was found in the Linux kernels traffic control (QoS) subsystem in     how a user triggers the qfq_change_class function with an incorrect MTU value of the network device used     as lmax. This flaw allows a local user to crash or potentially escalate their privileges on the     system.(CVE-2023-2248)

    qfq_change_class in net/sched/sch_qfq.c in the Linux kernel before 6.2.13 allows an out-of-bounds write     because lmax can exceed QFQ_MIN_LMAX.(CVE-2023-31436)

    A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in     SCSI sub-component in the Linux Kernel. In this flaw an attacker could leak kernel internal     information.(CVE-2023-2162)

    Copy_from_user on 64-bit versions of the Linux kernel does not implement the __uaccess_begin_nospec     allowing a user to bypass the 'access_ok' check and pass a kernel pointer to copy_from_user(). This would     allow an attacker to leak information. We recommend upgrading beyond     commit74e19ef0ff8061ef55957c3abd71614ef0f42f47(CVE-2023-0459)

    A null pointer dereference issue was found in the sctp network protocol in net/sctp/stream_sched.c in     Linux Kernel. If stream_in allocation is failed, stream_out is freed which would further be accessed. A     local user could use this flaw to crash the system or potentially cause a denial of     service.(CVE-2023-2177)

    A denial of service problem was found, due to a possible recursive locking scenario, resulting in a     deadlock in table_clear in drivers/md/dm-ioctl.c in the Linux Kernel Device Mapper-Multipathing sub-     component.(CVE-2023-2269)

    An out-of-bounds memory access flaw was found in the Linux kernels XFS file system in how a user     restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or     potentially escalate their privileges on the system.(CVE-2023-2124)

    A vulnerability was found in compare_netdev_and_ip in drivers/infiniband/core/cma.c in RDMA in the Linux     Kernel. The improper cleanup results in out-of-boundary read, where a local user can utilize this problem     to crash the system or escalation of privilege.(CVE-2023-2176)

    An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The     userspace 'data-block[0]' variable was not capped to a number between 0-255 and was used as the size of     a memcpy, possibly writing beyond the end of dma_buffer. This flaw could allow a local privileged user to     crash the system or potentially achieve code execution.(CVE-2023-2194)

    The Linux kernel allows userspace processes to enable mitigations by calling prctl with     PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed     that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to     attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be     observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened     because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that     STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection.
    However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons,     which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target     injection against which STIBP protects.(CVE-2023-1998)

    A flaw was found in the Linux kernel's udmabuf device driver. The specific flaw exists within a fault     handler. The issue results from the lack of proper validation of user-supplied data, which can result in a     memory access past the end of an array. An attacker can leverage this vulnerability to escalate privileges     and execute arbitrary code in the context of the kernel.(CVE-2023-2008)

    A use-after-free vulnerability in the Linux Kernel io_uring system can be exploited to achieve local     privilege escalation. The io_file_get_fixed function lacks the presence of ctx-uring_lock which can     lead to a Use-After-Free vulnerability due a race condition with fixed files getting unregistered. We     recommend upgrading past commit da24142b1ef9fd5d36b76e36bab328a5b27523e8.(CVE-2023-1872)

    A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
    This flaw allows a local user to cause an out-of-bounds write issue.(CVE-2022-1015)

    An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in     drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128     (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS).(CVE-2022-36280)

    An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4.(CVE-2023-30456)

    A use-after-free flaw was found in vhost_net_set_backend in drivers/vhost/net.c in virtio network     subcomponent in the Linux kernel due to a double fget. This flaw could allow a local attacker to crash the     system, and could even lead to a kernel information leak problem.(CVE-2023-1838)

    A flaw that boot CPU could be vulnerable for the speculative execution behavior kind of attacks in the     Linux kernel X86 CPU Power management options functionality was found in the way user resuming CPU from     suspend-to-RAM. A local user could use this flaw to potentially get unauthorized access to some memory of     the CPU similar to the speculative execution behavior kind of attacks.(CVE-2023-1637)

    A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some     uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an     information leak.(CVE-2023-1513)

    A double-free flaw was found in the Linux kernels TUN/TAP device driver functionality in how a user     registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw     allows a local user to crash or potentially escalate their privileges on the system.(CVE-2022-4744)

    Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege     Escalation.The imperfect hash area can be updated while packets are traversing, which will cause a use-     after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext.A local attacker user can use     this vulnerability to elevate its privileges to root.This issue affects Linux Kernel: from 4.14 before git     commit ee059170b1f7e94e55fa6cadee544e176a6e59c2.(CVE-2023-1281)

    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference).(CVE-2023-28466)

    A use-after-free flaw was found in the Linux kernels core dump subsystem. This flaw allows a local user     to crash the system. Only if patch 390031c94211 ('coredump: Use the vma snapshot in fill_files_note') not     applied yet, then kernel could be affected.(CVE-2023-1249)

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

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

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 version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0340 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2020-27820:
    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-2021-0920:
    In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. 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-196926917References:
    Upstream kernel

    CVE-2021-20321:
    A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.

    CVE-2021-22543:
    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-2021-38160:
    ** 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-2021-38199:
    fs/nfs/nfs4client.c in the Linux kernel before 5.13.4 has incorrect connection-setup ordering, which     allows operators of remote NFSv4 servers to cause a denial of service (hanging of mounts) by arranging for     those servers to be unreachable during trunking detection.

    CVE-2021-45868:
    In the Linux kernel before 5.15.3, fs/quota/quota_tree.c does not validate the block number in the quota     tree (on disk). This can, for example, lead to a kernel/locking/rwsem.c use-after-free if there is a     corrupted quota file.

    CVE-2022-0617:

    CVE-2022-2196:
    A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution     attacks.L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or     IBPBafter running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code     execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2     or past commit2e7eab81425a


    CVE-2022-2639:
    An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of     actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size()     function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This     flaw allows a local user to crash or potentially escalate their privileges on the system.

    CVE-2022-29581:
    Improper Update of Reference Count vulnerability in net/sched of Linux Kernel allows local attacker to     cause privilege escalation to root. This issue affects: Linux Kernel versions prior to 5.18; version 4.14     and later versions.

    CVE-2022-3567:
    A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects     the function inet6_stream_ops/inet6_dgram_ops of the component IPv6 Handler. The manipulation leads to     race condition. It is recommended to apply a patch to fix this issue. VDB-211090 is the identifier     assigned to this vulnerability.

    CVE-2022-3586:
    A flaw was found in the Linux kernels networking code. A use-after-free was found in the way the     sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and     freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a     denial of service.

    CVE-2022-4129:
    A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing     sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw     to potentially crash the system causing a denial of service.

    CVE-2022-41858:
    A flaw was found in the Linux kernel. A NULL pointer dereference may occur while a slip driver is in     progress to detach in sl_tx_timeout in drivers/net/slip/slip.c. This issue could allow an attacker to     crash the system or leak internal kernel information.

    CVE-2022-4378:
    A stack overflow flaw was found in the Linux kernel/'s SYSCTL subsystem in how a user changes certain     kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their     privileges on the system.

    CVE-2023-0045:
    The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The     ib_prctl_set function updates the Thread Information Flags (TIFs) for the task and updates the SPEC_CTRL     MSR on the function __speculation_ctrl_update, but the IBPB is only issued on the next schedule, when the     TIF bits are checked. This leaves the victim vulnerable to values already injected on the BTB, prior to     the prctl syscall. The patch that added the support for the conditional mitigation via prctl     (ib_prctl_set) dates back to the kernel 4.9.176.

    We recommend upgrading past commita664ec9158eeddd75121d39c9a0758016097fa96

This issue could occur     when assoc_info->req_len data is bigger than the size of the buffer, defined as WL_EXTRA_BUF_MAX, leading     to a denial of service.

    CVE-2023-26545:
    In the Linux kernel before 6.1.13, there is a double free in net/mpls/af_mpls.c upon an allocation failure     (for registering the sysctl table under a new location) during the renaming of a device.

    CVE-2023-28466:
    do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading     to a race condition (with a resultant use-after-free or NULL pointer dereference).

    CVE-2023-30456:
    An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64     lacks consistency checks for CR0 and CR4.

    CVE-2023-32233:
    In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests     can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users     can obtain root privileges. This occurs because anonymous sets are mishandled.
