Tenable has extracted the preceding description block directly from the Oracle 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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel 4.15.0, a NULL pointer dereference was discovered in hfs_ext_read_extent in hfs.ko.
    This can occur during a mount of a crafted hfs filesystem. (CVE-2018-12928)

Note that Nessus relies on the presence of the package as reported by the vendor.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc. Security Fix(es):A vulnerability was found     in the Linux Kernel where the function sunkbd_reinit     having been scheduled by sunkbd_interrupt before sunkbd     being freed. Though the dangling pointer is set to NULL     in sunkbd_disconnect, there is still an alias in     sunkbd_reinit causing Use After Free.(CVE-2020-25669)An     issue was discovered in the Linux kernel through 5.9.1,     as used with Xen through 4.14.x.
    drivers/xen/events/events_base.c allows event-channel     removal during the event-handling loop (a race     condition). This can cause a use-after-free or NULL     pointer dereference, as demonstrated by a dom0 crash     via events for an in-reconfiguration paravirtualized     device, aka CID-073d0552ead5.(CVE-2020-27675)An issue     was discovered in the Linux kernel through 5.9.1, as     used with Xen through 4.14.x. Guest OS users can cause     a denial of service (host OS hang) via a high rate of     events to dom0, aka CID-e99502f76271.(CVE-2020-27673)An     issue was discovered in __split_huge_pmd in     mm/huge_memory.c in the Linux kernel before 5.7.5. The     copy-on-write implementation can grant unintended write     access because of a race condition in a THP mapcount     check, aka CID-c444eb564fb1.(CVE-2020-29368)An issue     was discovered in     drivers/accessibility/speakup/spk_ttyio.c in the Linux     kernel through 5.9.9. Local attackers on systems with     the speakup driver could cause a local denial of     service attack, aka CID-d41227544427. This occurs     because of an invalid free when the line discipline is     used more than once.(CVE-2020-28941)** DISPUTED **     fsfsd fs3xdr.c in the Linux kernel through 5.10.8, when     there is an NFS export of a subdirectory of a     filesystem, allows remote attackers to traverse to     other parts of the filesystem via READDIRPLUS. NOTE:
    some parties argue that such a subdirectory export is     not intended to prevent this attack see also the     exports(5) no_subtree_check default     behavior.(CVE-2021-3178)An issue was discovered in the     Linux kernel through 5.11.3.
    drivers/scsi/scsi_transport_iscsi.c is adversely     affected by the ability of an unprivileged user to     craft Netlink messages.(CVE-2021-27364)An issue was     discovered in the Linux kernel through 5.11.3. A kernel     pointer leak can be used to determine the address of     the iscsi_transport structure. When an iSCSI transport     is registered with the iSCSI subsystem, the transport's     handle is available to unprivileged users via the sysfs     file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)ntfs_read_locked_inode     in the ntfs.ko filesystem driver in the Linux kernel     4.15.0 allows attackers to trigger a use-after-free     read and possibly cause a denial of service (kernel     oops or panic) via a crafted ntfs     filesystem.(CVE-2018-12929)In the Linux kernel 4.15.0,     a NULL pointer dereference was discovered in     hfs_ext_read_extent in hfs.ko. This can occur during a     mount of a crafted hfs     filesystem.(CVE-2018-12928)rtw_wx_set_scan in     drivers/staging/rtl8188eu/os_dep/ioctl_linux.c in the     Linux kernel through 5.11.6 allows writing beyond the     end of the ->ssid[] array. NOTE: from the perspective     of kernel.org releases, CVE IDs are not normally used     for drivers/staging/* (unfinished work) however, system     integrators may have situations in which a     drivers/staging issue is relevant to their own customer     base.(CVE-2021-28660)There is a flaw reported in the     Linux kernel in versions before 5.9 in drivers/gpu/drm     ouveau ouveau_sgdma.c in nouveau_sgdma_create_ttm in     Nouveau DRM subsystem. The issue results from the lack     of validating the existence of an object prior to     performing operations on the object. An attacker with a     local account with a root privilege, can leverage this     vulnerability to escalate privileges and execute code     in the context of the kernel.(CVE-2021-20292)A flaw was     found in the Nosy driver in the Linux kernel. This     issue allows a device to be inserted twice into a     doubly-linked list, leading to a use-after-free when     one of these devices is removed. The highest threat     from this vulnerability is to confidentiality,     integrity, as well as system availability. Versions     before kernel 5.12-rc6 are affected(CVE-2021-3483)In     drivers/pci/hotplug/rpadlpar_sysfs.c in the Linux     kernel through 5.11.8, the RPA PCI Hotplug driver has a     user-tolerable buffer overflow when writing a new     device name to the driver from userspace, allowing     userspace to write data to the kernel stack frame     directly. This occurs because add_slot_store and     remove_slot_store mishandle drc_name '\0' termination,     aka CID-cc7a0bb058b8.(CVE-2021-28972)A race condition     was discovered in get_old_root in fs/btrfs/ctree.c in     the Linux kernel through 5.11.8. It allows attackers to     cause a denial of service (BUG) because of a lack of     locking on an extent buffer before a cloning operation,     aka CID-dbcc7d57bffc.(CVE-2021-28964)An issue was     discovered in the Linux kernel before 5.11.7.
    usbip_sockfd_store in drivers/usb/usbip/stub_dev.c     allows attackers to cause a denial of service (GPF)     because the stub-up sequence has race conditions during     an update of the local and shared status, aka     CID-9380afd6df70.(CVE-2021-29265)The fix for XSA-365     includes initialization of pointers such that     subsequent cleanup code wouldn't use uninitialized or     stale values. This initialization went too far and may     under certain conditions also overwrite pointers which     are in need of cleaning up. The lack of cleanup would     result in leaking persistent grants. The leak in turn     would prevent fully cleaning up after a respective     guest has died, leaving around zombie domains. All     Linux versions having the fix for XSA-365 applied are     vulnerable. XSA-365 was classified to affect versions     back to at least 3.11.(CVE-2021-28688)An issue was     discovered in the Linux kernel before 5.11.3 when a     webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak     for large arguments, aka     CID-fb18802a338b.(CVE-2021-30002)An issue was     discovered in the Linux kernel before 5.8.10.
    virt/kvm/kvm_main.c has a kvm_io_bus_unregister_dev     memory leak upon a kmalloc failure, aka     CID-f65886606c2d.(CVE-2020-36312)An issue was     discovered in the Linux kernel before 5.9.
    arch/x86/kvm/svm/sev.c allows attackers to cause a     denial of service (soft lockup) by triggering     destruction of a large SEV VM (which requires     unregistering many encrypted regions), aka     CID-7be74942f184.(CVE-2020-36311)An issue was     discovered in the Linux kernel before 5.11.11.
    qrtr_recvmsg in net/qrtr/qrtr.c allows attackers to     obtain sensitive information from kernel memory because     of a partially uninitialized data structure, aka     CID-50535249f624.(CVE-2021-29647)An issue was     discovered in the Linux kernel through 5.11.10.
    driverset/ethernet/freescale/gianfar.c in the Freescale     Gianfar Ethernet driver allows attackers to cause a     system crash because a negative fragment size is     calculated in situations involving an rx queue overrun     when jumbo packets are used and NAPI is enabled, aka     CID-d8861bab48b6.(CVE-2021-29264)An out-of-bounds (OOB)     memory access flaw was found in x25_bind in     net/x25/af_x25.c in the Linux kernel version v5.12-rc5.
    A bounds check failure allows a local attacker with a     user account on the system 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 confidentiality,     integrity, as well as system     availability.(CVE-2020-35519)An issue was discovered in     the Linux kernel before 5.11.8. kernel/bpf/verifier.c     has an off-by-one error (with a resultant integer     underflow) affecting out-of-bounds speculation on     pointer arithmetic, leading to side-channel attacks     that defeat Spectre mitigations and obtain sensitive     information from kernel memory, aka     CID-10d2bb2e6b1d.(CVE-2020-27171)An issue was     discovered in the Linux kernel before 5.11.8.
    kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic,     leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from     kernel memory, aka CID-f232326f6966. This affects     pointer types that do not define a     ptr_limit.(CVE-2020-27170)BPF JIT compilers in the     Linux kernel through 5.11.12 have incorrect computation     of branch displacements, allowing them to execute     arbitrary code within the kernel context. This affects     arch/x86 et/bpf_jit_comp.c and arch/x86     et/bpf_jit_comp32.c.(CVE-2021-29154)A race condition in     Linux kernel SCTP sockets (net/sctp/socket.c) before     5.12-rc8 can lead to kernel privilege escalation from     the context of a network service or an unprivileged     process. If sctp_destroy_sock is called without     sock_net(sk)->sctp.addr_wq_lock then an element is     removed from the auto_asconf_splist list without any     proper locking. This can be exploited by an attacker     with network service privileges to escalate to root or     from the context of an unprivileged user directly if a     BPF_CGROUP_INET_SOCK_CREATE is attached which denies     creation of some SCTP socket.(CVE-2021-23133)An issue     was discovered in the FUSE filesystem implementation in     the Linux kernel before 5.10.6, aka CID-5d069dbe8aaf.
    fuse_do_getattr() calls make_bad_inode() in     inappropriate situations, causing a system crash. NOTE:
    the original fix for this vulnerability was incomplete,     and its incompleteness is tracked as     CVE-2021-28950.(CVE-2020-36322)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)An issue was     discovered in the Linux kernel through 5.11.x.
    kernel/bpf/verifier.c performs undesirable     out-of-bounds speculation on pointer arithmetic,     leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from     kernel memory. Specifically, for sequences of pointer     arithmetic operations, the pointer modification     performed by the first operation is not correctly     accounted for when restricting subsequent     operations.(CVE-2021-29155)kernel/bpf/verifier.c in the     Linux kernel through 5.12.1 performs undesirable     speculative loads, leading to disclosure of stack     content via side-channel attacks, aka CID-801c6058d14a.
    The specific concern is not protecting the BPF stack     area against speculative loads. Also, the BPF stack can     contain uninitialized data that might represent     sensitive information previously operated on by the     kernel.(CVE-2021-31829)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)kernel/bpf/verifier.c in the     Linux kernel through 5.12.7 enforces incorrect limits     for pointer arithmetic operations, aka     CID-bb01a1bba579. This can be abused to perform     out-of-bounds reads and writes in kernel memory,     leading to local privilege escalation to root. In     particular, there is a corner case where the off reg     causes a masking direction change, which then results     in an incorrect final aux->alu_limit.(CVE-2021-33200)An     issue was discovered in the Linux kernel through     5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can     exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI,     and has a length up to the maximum length of a Netlink     message.(CVE-2021-27365)

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the Linux kernel's implementation     of string matching within a packet. A privileged user     (with root or CAP_NET_ADMIN) when inserting iptables     rules could insert a rule which can panic the     system.(CVE-2021-20177)

  - rtw_wx_set_scan in     drivers/staging/rtl8188eu/os_dep/ioctl_linux.c in the     Linux kernel through 5.11.6 allows writing beyond the     end of the ->ssid[] array. NOTE: from the perspective     of kernel.org releases, CVE IDs are not normally used     for drivers/staging/* (unfinished work) however, system     integrators may have situations in which a     drivers/staging issue is relevant to their own customer     base.(CVE-2021-28660)

  - There is a flaw reported in     drivers/gpu/drm/nouveau/nouveau_sgdma.c in     nouveau_sgdma_create_ttm in Nouveau DRM subsystem. The     issue results from the lack of validating the existence     of an object prior to performing operations on the     object. An attacker with a local account with a root     privilege, can leverage this vulnerability to escalate     privileges and execute code in the context of the     kernel.(CVE-2021-20292)

  - ntfs_read_locked_inode in the ntfs.ko filesystem driver     in the Linux kernel 4.15.0 allows attackers to trigger     a use-after-free read and possibly cause a denial of     service (kernel oops or panic) via a crafted ntfs     filesystem.(CVE-2018-12929)

  - In the Linux kernel 4.15.0, a NULL pointer dereference     was discovered in hfs_ext_read_extent in hfs.ko. This     can occur during a mount of a crafted hfs     filesystem.(CVE-2018-12928)

  - An issue was discovered in the Linux kernel through     5.11.3. A kernel pointer leak can be used to determine     the address of the iscsi_transport structure. When an     iSCSI transport is registered with the iSCSI subsystem,     the transport's handle is available to unprivileged     users via the sysfs file system, at     /sys/class/iscsi_transport/$TRANSPORT_NAME/handle. When     read, the show_transport_handle function (in     drivers/scsi/scsi_transport_iscsi.c) is called, which     leaks the handle. This handle is actually the pointer     to an iscsi_transport struct in the kernel module's     global variables.(CVE-2021-27363)

  - An issue was discovered in the Linux kernel through     5.11.3. drivers/scsi/scsi_transport_iscsi.c is     adversely affected by the ability of an unprivileged     user to craft Netlink messages.(CVE-2021-27364)

  - An issue was discovered in the Linux kernel through     5.11.3. Certain iSCSI data structures do not have     appropriate length constraints or checks, and can     exceed the PAGE_SIZE value. An unprivileged user can     send a Netlink message that is associated with iSCSI,     and has a length up to the maximum length of a Netlink     message.(CVE-2021-27365)

  - nbd_add_socket in drivers/block/nbd.c in the Linux     kernel through 5.10.12 has an ndb_queue_rq     use-after-free that could be triggered by local     attackers (with access to the nbd device) via an I/O     request at a certain point during device setup, aka     CID-b98e762e3d71.(CVE-2021-3348)

  - An issue was discovered in the Linux kernel through     5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute     code in the kernel, aka     CID-34b1a1ce1458.(CVE-2021-3347)

  - fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8,     when there is an NFS export of a subdirectory of a     filesystem, allows remote attackers to traverse to     other parts of the filesystem via READDIRPLUS. NOTE:
    some parties argue that such a subdirectory export is     not intended to prevent this attack see also the     exports(5) no_subtree_check default     behavior.(CVE-2021-3178)

  - In tun_get_user of tun.c, there is possible memory     corruption due to a use after free. This could lead to     local escalation of privilege with System execution     privileges required. User interaction is not required     for exploitation.(CVE-2021-0342)
