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

  - The usbvision driver in the Linux kernel package 3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red     Hat Enterprise Linux (RHEL) 7.1 allows physically proximate attackers to cause a denial of service (panic)     via a nonzero bInterfaceNumber value in a USB device descriptor. (CVE-2015-7833)

  - arch/arm64/kernel/sys.c in the Linux kernel before 4.0 allows local users to bypass the 'strict page     permissions' protection mechanism and modify the system-call table, and consequently gain privileges, by     leveraging write access. (CVE-2015-8967)

  - In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in     drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the     userspace API. However, the code allows larger values such as 23. (CVE-2015-9289)

  - The evm_verify_hmac function in security/integrity/evm/evm_main.c in the Linux kernel before 4.5 does not     properly copy data, which makes it easier for local users to forge MAC values via a timing side-channel     attack. (CVE-2016-2085)

  - The rtnl_fill_link_ifmap function in net/core/rtnetlink.c in the Linux kernel before 4.5.5 does not     initialize a certain data structure, which allows local users to obtain sensitive information from kernel     stack memory by reading a Netlink message. (CVE-2016-4486)

  - Race condition in the sclp_ctl_ioctl_sccb function in drivers/s390/char/sclp_ctl.c in the Linux kernel     before 4.6 allows local users to obtain sensitive information from kernel memory by changing a certain     length value, aka a 'double fetch' vulnerability. (CVE-2016-6130)

  - A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost     functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A     privileged guest user able to pass descriptors with invalid length to the host when migration is underway,     could use this flaw to increase their privileges on the host. (CVE-2019-14835)

  - In do_epoll_ctl and ep_loop_check_proc of eventpoll.c, there is a possible use after free due to a logic     error. This could lead to local escalation of privilege with no additional execution privileges needed.
    User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
    A-147802478References: Upstream kernel (CVE-2020-0466)

  - A race condition was found in the Linux kernels implementation of the floppy disk drive controller driver     software. The impact of this issue is lessened by the fact that the default permissions on the floppy     device (/dev/fd0) are restricted to root. If the permissions on the device have changed the impact changes     greatly. In the default configuration root (or equivalent) permissions are required to attack this flaw.
    (CVE-2021-20261)

  - There is a flaw reported in the Linux kernel in versions before 5.9 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)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - 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)

  - 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)

  - ** DISPUTED ** 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)

  - 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)

  - 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/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)

  - 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)

  - kernel/module.c in the Linux kernel before 5.12.14 mishandles Signature Verification, aka     CID-0c18f29aae7c. Without CONFIG_MODULE_SIG, verification that a kernel module is signed, for loading via     init_module, does not occur for a module.sig_enforce=1 command-line argument. (CVE-2021-35039)

    (CVE-2021-20219)

  - A race condition was found in the Linux kernels implementation of the floppy disk drive controller driver     software. The impact of this issue is lessened by the fact that the default permissions on the floppy     device (/dev/fd0) are restricted to root. If the permissions on the device have changed the impact changes     greatly. In the default configuration root (or equivalent) permissions are required to attack this flaw.
    (CVE-2021-20261)

  - 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)

  - 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 5.11.11. The netfilter subsystem allows attackers to     cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h     lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.

The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4904-1 advisory.

  - The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr     operations that underspecifies removing extended privilege attributes, which allows local users to cause a     denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by     using chown to remove a capability from the ping or Wireshark dumpcap program. (CVE-2015-1350)

  - The hdpvr_probe function in drivers/media/usb/hdpvr/hdpvr-core.c in the Linux kernel through 4.13.11     allows local users to cause a denial of service (improper error handling and system crash) or possibly     have unspecified other impact via a crafted USB device. (CVE-2017-16644)

  - The time subsystem in the Linux kernel through 4.9.9, when CONFIG_TIMER_STATS is enabled, allows local     users to discover real PID values (as distinguished from PID values inside a PID namespace) by reading the     /proc/timer_list file, related to the print_timer function in kernel/time/timer_list.c and the
    __timer_stats_timer_set_start_info function in kernel/time/timer.c. (CVE-2017-5967)

  - An issue was discovered in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.17.3. A denial of     service (memory corruption and BUG) can occur for a corrupted xfs image upon encountering an inode that is     in extent format, but has more extents than fit in the inode fork. (CVE-2018-13095)

  - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,     leading to a NULL pointer dereference. (CVE-2019-16231)

  - drivers/net/wireless/marvell/libertas/if_sdio.c in the Linux kernel 5.2.14 does not check the     alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16232)

  - A memory leak in the adis_update_scan_mode_burst() function in drivers/iio/imu/adis_buffer.c in the Linux     kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka     CID-9c0530e898f3. (CVE-2019-19061)

  - A race condition was found in the Linux kernels implementation of the floppy disk drive controller driver     software.

    (CVE-2021-20261)

  - An issue was discovered in the Linux kernel 3.11 through 5.10.16, as used by Xen. To service requests to     the PV backend, the driver maps grant references provided by the frontend. In this process, errors may be     encountered. In one case, an error encountered earlier might be discarded by later processing, resulting     in the caller assuming successful mapping, and hence subsequent operations trying to access space that     wasn't mapped. In another case, internal state would be insufficiently updated, preventing safe recovery     from the error. This affects drivers/block/xen-blkback/blkback.c. (CVE-2021-26930)

  - An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI     backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially     being at least under the influence of guests (such as out of memory conditions), it isn't correct to     assume a plain bug. Memory allocations potentially causing such crashes occur only when Linux is running     in PV mode, though. This affects drivers/block/xen-blkback/blkback.c and drivers/xen/xen-scsiback.c.
    (CVE-2021-26931)

  - An issue was discovered in the Linux kernel through 5.11.3, as used with Xen PV. A certain part of the     netback driver lacks necessary treatment of errors such as failed memory allocations (as a result of     changes to the handling of grant mapping errors). A host OS denial of service may occur during misbehavior     of a networking frontend driver. NOTE: this issue exists because of an incomplete fix for CVE-2021-26931.

    (CVE-2021-20261)

  - 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)

A local user could use this flaw to crash     the system or escalate their privileges on the     system.(CVE-2021-3573)

  - 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)

  - A vulnerability was found in Linux kernel where     non-blocking socket in llcp_sock_connect() leads to     leak and eventually hanging-up the     system.(CVE-2020-25673)

  - net/bluetooth/hci_request.c in the Linux kernel through     5.12.2 has a race condition for removal of the HCI     controller.(CVE-2021-32399)

  - In all Qualcomm products with Android releases from CAF     using the Linux kernel, during DMA allocation, due to     wrong data type of size, allocation size gets truncated     which makes allocation succeed when it should     fail.(CVE-2017-9725)

  - A flaw double-free memory corruption in the Linux     kernel HCI device initialization subsystem was found in     the way user attach malicious HCI TTY Bluetooth device.
    A local user could use this flaw to crash the system.
    This flaw affects all the Linux kernel versions     starting from 3.13.(CVE-2021-3564)

  - A flaw was found in the CAN BCM networking protocol in     the Linux kernel, where a local attacker can abuse a     flaw in the CAN subsystem to corrupt memory, crash the     system or escalate privileges.(CVE-2021-3609)

  - The ip6gre_err function in net/ipv6/ip6_gre.c in the     Linux kernel allows remote attackers to have     unspecified impact via vectors involving GRE flags in     an IPv6 packet, which trigger an out-of-bounds     access.(CVE-2017-5897)

  - An Out-of-Bounds Read was discovered in     arch/arm/mach-footbridge/personal-pci.c in the Linux     kernel through 5.12.11 because of the lack of a check     for a value that shouldn't be negative, e.g., access to     element -2 of an array, aka     CID-298a58e165e4.(CVE-2021-32078)

  - In the Linux kernel before 4.20.8,     kvm_ioctl_create_device in virt/kvm/kvm_main.c     mishandles reference counting because of a race     condition, leading to a use-after-free.(CVE-2019-6974)

  - In uvc_scan_chain_forward of uvc_driver.c, there is a     possible linked list corruption due to an unusual root     cause. This could lead to local escalation of privilege     in the kernel with no additional execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2020-0404)

  - In create_pinctrl of core.c, there is a possible out of     bounds read due to a use after free. This could lead to     local information disclosure with no additional     execution privileges needed. User interaction is not     needed for exploitation.(CVE-2020-0427)

  - In kbd_keycode of keyboard.c, there is a possible out     of bounds write due to a missing bounds check. This     could lead to local escalation of privilege with no     additional execution privileges needed. User     interaction is not needed for exploitation.Product:
    AndroidVersions: Android kernelAndroid ID:
    A-144161459(CVE-2020-0431)

  - In blk_mq_queue_tag_busy_iter of blk-mq-tag.c, there is     a possible use after free due to improper locking. This     could lead to local escalation of privilege with no     additional execution privileges needed. User     interaction is not needed for     exploitation.(CVE-2020-0433)

  - In various methods of hid-multitouch.c, there is a     possible out of bounds write due to a missing bounds     check. This could lead to local escalation of privilege     with no additional execution privileges needed. User     interaction is not needed for     exploitation.(CVE-2020-0465)

  - 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)
