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

  - 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.Product:
    AndroidVersions: Android kernelAndroid ID:
    A-162844689References: Upstream kernel(CVE-2020-0465)

  - 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 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)

  - In fs/ocfs2/cluster/nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216)

  - 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)

  - 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)

According to the versions of the kernel packages installed, the EulerOS 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 flaw was found in Linux     kernel in the ext4 filesystem code. A use-after-free is     possible in ext4_ext_remove_space() function when     mounting and operating a crafted ext4     image.(CVE-2018-10876)A flaw was found in the Linux     kernel. A use-after-free was found in the way the     console subsystem was using ioctls KDGKBSENT and     KDSKBSENT. A local user could use this flaw to get read     memory access out of bounds. The highest threat from     this vulnerability is to data     confidentiality.(CVE-2020-25656)A flaw was found in the     way RTAS handled memory accesses in userspace to kernel     communication. On a locked down (usually due to Secure     Boot) guest system running on top of PowerVM or KVM     hypervisors (pseries platform) a root like local user     could use this flaw to further increase their     privileges to that of a running     kernel.(CVE-2020-27777)A information disclosure     vulnerability in the Upstream kernel encrypted-keys.
    Product: Android. Versions: Android kernel. Android ID:
    A-70526974.(CVE-2017-13305)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)An issue     was discovered in dlpar_parse_cc_property in     arch/powerpc/platforms/pseries/dlpar.c in the Linux     kernel through 5.1.6. There is an unchecked kstrdup of     prop->name, which might allow an attacker to cause a     denial of service (NULL pointer dereference and system     crash).(CVE-2019-12614)An issue was discovered in     fs/xfs/xfs_icache.c in the Linux kernel through 4.17.3.
    There is a NULL pointer dereference and panic in     lookup_slow() on a NULL inode->i_ops pointer when doing     pathwalks on a corrupted xfs image. This occurs because     of a lack of proper validation that cached inodes are     free during allocation.(CVE-2018-13093)An issue was     discovered in rds_tcp_kill_sock in net/rds/tcp.c in the     Linux kernel before 5.0.8. There is a race condition     leading to a use-after-free, related to net namespace     cleanup.(CVE-2019-11815)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. 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 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 yurex_read in drivers/usb/misc/yurex.c in     the Linux kernel before 4.17.7. Local attackers could     use user access read/writes with incorrect bounds     checking in the yurex USB driver to crash the kernel or     potentially escalate     privileges.(CVE-2018-16276)drivers/infiniband/core/ucma     .c in the Linux kernel through 4.17.11 allows     ucma_leave_multicast to access a certain data structure     after a cleanup step in ucma_process_join, which allows     attackers to cause a denial of service     (use-after-free).(CVE-2018-14734)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.

    Upstream kernel(CVE-2020-0465)It was found that the raw     midi kernel driver does not protect against concurrent     access which leads to a double realloc (double free) in     snd_rawmidi_input_params() and     snd_rawmidi_output_status() which are part of     snd_rawmidi_ioctl() handler in rawmidi.c file. A     malicious local attacker could possibly use this for     privilege escalation.(CVE-2018-10902)Linux kernel ext4     filesystem is vulnerable to an out-of-bound access in     the ext4_ext_drop_refs() function when operating on a     crafted ext4 filesystem image.(CVE-2018-10877)Linux     kernel is vulnerable to a stack-out-of-bounds write in     the ext4 filesystem code when mounting and writing to a     crafted ext4 image in ext4_update_inline_data(). An     attacker could use this to cause a system crash and a     denial of service.(CVE-2018-10880)Linux Kernel contains     an out-of-bounds read flaw in the asn1_ber_decoder()     function in lib/asn1_decoder.c that is triggered when     decoding ASN.1 data. This may allow a remote attacker     to disclose potentially sensitive memory     contents.(CVE-2018-9383)use-after-free read in     sunkbd_reinit in     drivers/input/keyboard/sunkbd.c(CVE-2020-25669)mwifiex_     cmd_802_11_ad_hoc_start in drivers/     net/wireless/marvell/mwifiex/join.c in the Linux kernel     through 5.10.4 might allow remote attackers to execute     arbitrary code via a long SSID value, aka     CID-5c455c5ab332.(CVE-2020-36158)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 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)The KVM implementation in     the Linux kernel through 4.20.5 has a     Use-after-Free.(CVE-2019-7221)A flaw was found in the     JFS filesystem code. This flaw allows a local attacker     with the ability to set extended attributes to panic     the system, causing memory corruption or escalating     privileges. The highest threat from this vulnerability     is to confidentiality, integrity, as well as system     availability.(CVE-2020-27815)An out-of-bounds (OOB)     memory access flaw was found in x25_bind in     net/x25/af_x25.c in the Linux kernel. 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)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 NULL pointer     dereference was found in the net/rds/rdma.c

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 :

  - An information-leak vulnerability was found in the     kernel when it truncated a file to a smaller size which     consisted of an inline extent that was compressed. The     data between the new file size and the old file size     was not discarded and the number of bytes used by the     inode were not correctly decremented, which gave the     wrong report for callers of the stat(2) syscall. This     wasted metadata space and allowed for the truncated     data to be leaked, and data corruption or loss to     occur. A caller of the clone ioctl could exploit this     flaw by using only standard file-system operations     without root access to read the truncated     data.(CVE-2015-8374i1/4%0

  - crypto/pcrypt.c in the Linux kernel, before 4.14.13,     mishandles freeing instances, allowing a local user     able to access the AF_ALG-based AEAD interface     (CONFIG_CRYPTO_USER_API_AEAD) and pcrypt     (CONFIG_CRYPTO_PCRYPT) to cause a denial of service     (kfree of an incorrect pointer) or possibly have     unspecified other impact by executing a crafted     sequence of system calls. Due to the nature of the     flaw, privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2017-18075i1/4%0

  - An elevation of privilege vulnerability in the Qualcomm     Wi-Fi driver could enable a local malicious application     to execute arbitrary code within the context of the     kernel. This issue is rated as High because it first     requires compromising a privileged process. Product:
    Android. Versions: N/A. Android ID: A-32835279.
    References: QC-CR#1096945.(CVE-2017-0523i1/4%0

  - The saa7164_bus_get function in     drivers/media/pci/saa7164/saa7164-bus.c in the Linux     kernel through 4.10.14 allows local users to cause a     denial of service (out-of-bounds array access) or     possibly have unspecified other impact by changing a     certain sequence-number value, aka a 'double fetch'     vulnerability.(CVE-2017-8831i1/4%0

  - A flaw was found in the way the Linux kernel's splice()     system call validated its parameters. On certain file     systems, a local, unprivileged user could use this flaw     to write past the maximum file size, and thus crash the     system.(CVE-2014-7822i1/4%0

  - The vc4_get_bcl function in     drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM     driver in the Linux kernel before 4.9.7 does not set an     errno value upon certain overflow detections allowing     local users to cause a denial of service (incorrect     pointer dereference and OOPS) via inconsistent size     values in a VC4_SUBMIT_CL ioctl call.(CVE-2017-5577i1/4%0

  - In fs/ocfs2/cluster/nodemanager.c in the Linux kernel     before 4.15, local users can cause a denial of service     (NULL pointer dereference and BUG) because a required     mutex is not used.(CVE-2017-18216i1/4%0

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets     implementation in the Linux kernel networking subsystem     handled synchronization while creating the TPACKET_V3     ring buffer. A local user able to open a raw packet     socket (requires the CAP_NET_RAW capability) could use     this flaw to elevate their privileges on the     system.(CVE-2016-8655i1/4%0

  - An exploitable memory corruption flaw was found in the     Linux kernel. The append path can be erroneously     switched from UFO to non-UFO in ip_ufo_append_data()     when building an UFO packet with MSG_MORE option. If     unprivileged user namespaces are available, this flaw     can be exploited to gain root     privileges.(CVE-2017-1000112i1/4%0

  - A security flaw was found in the Linux kernel in a way     that the cleancache subsystem clears an inode after the     final file truncation (removal). The new file created     with the same inode may contain leftover pages from     cleancache and the old file data instead of the new     one.(CVE-2018-16862i1/4%0

  - arch/arm64/ include /asm/pgtable.h in the Linux kernel     before 3.15-rc5-next-20140519, as used in Android     before 2016-07-05 on Nexus 5X and 6P devices,     mishandles execute-only pages, which allows attackers     to gain privileges via a crafted application, aka     Android internal bug 28557020.(CVE-2014-9803i1/4%0

  - A heap-buffer overflow vulnerability was found in the     arcmsr_iop_message_xfer() function in     'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux     kernel through 4.8.2. The function does not restrict a     certain length field, which allows local users to gain     privileges or cause a denial of service via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can     potentially cause kernel heap corruption and arbitrary     kernel code execution.(CVE-2016-7425i1/4%0

  - An issue was discovered in the Linux kernel before     4.18.11. The ipddp_ioctl function in     drivers/net/appletalk/ipddp.c allows local users to     obtain sensitive kernel address information by     leveraging CAP_NET_ADMIN to read the ipddp_route dev     and next fields via an SIOCFINDIPDDPRT ioctl     call.(CVE-2018-20511i1/4%0

  - A memory leak in the irda_bind function in     net/irda/af_irda.c in the Linux kernel, through 4.16,     allows local users to cause a denial of service due to     a memory consumption by repeatedly binding an AF_IRDA     socket.(CVE-2018-6554i1/4%0

  - sound/core/timer.c in the Linux kernel before 4.4.1     employs a locking approach that does not consider slave     timer instances, which allows local users to cause a     denial of service (race condition, use-after-free, and     system crash) via a crafted ioctl     call.(CVE-2016-2547i1/4%0

  - Buffer overflow in the complete_emulated_mmio function     in arch/x86/kvm/x86.c in the Linux kernel before 3.13.6     allows guest OS users to execute arbitrary code on the     host OS by leveraging a loop that triggers an invalid     memory copy affecting certain cancel_work_item     data.(CVE-2014-0049i1/4%0

  - An issue was discovered in the F2FS filesystem code in     the Linux kernel in fs/f2fs/inode.c. A denial of     service due to a slab out-of-bounds read can occur for     a crafted f2fs filesystem image in which FI_EXTRA_ATTR     is set in an inode.(CVE-2018-13098i1/4%0

  - A vulnerability was found in the Linux kernel where     having malicious IP options present would cause the     ipv4_pktinfo_prepare() function to drop/free the dst.
    This could result in a system crash or possible     privilege escalation.(CVE-2017-5970i1/4%0

  - In the Linux kernel's vmw_gb_surface_define_ioctl()     function, in 'drivers/gpu/drm/vmwgfx/vmwgfx_surface.c'     file, a 'req-i1/4zmip_levels' is a user-controlled value     which is later used as a loop count limit. This allows     local unprivileged user to cause a denial of service by     a kernel lockup via a crafted ioctl call for a     '/dev/dri/renderD*' device.(CVE-2017-7346i1/4%0

  - It was found that the NFSv4 server in the Linux kernel     did not properly validate layout type when processing     NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. A     remote attacker could use this flaw to soft-lockup the     system and thus cause denial of     service.(CVE-2017-8797i1/4%0

  - CVE-2018-6927     Li Jinyue reported that the FUTEX_REQUEUE operation on     futexes did not check for negative parameter values,     which might lead to a denial of service or other     security impact.

  - CVE-2018-7492     The syzkaller tool found that the RDS protocol was     lacking a null pointer check. A local attacker on a     system with the rds module loaded could use this for     denial of service.

  - CVE-2018-7566     Fan LongFei reported a race condition in the ALSA     (sound) sequencer core, between write and ioctl     operations. This could lead to an out-of-bounds access     or use-after-free. A local user with access to a     sequencer device could use this for denial of service or     possibly for privilege escalation.

  - CVE-2018-7740     Nic Losby reported that the hugetlbfs filesystem's mmap     operation did not properly range-check the file offset.
    A local user with access to files on a hugetlbfs     filesystem could use this to cause a denial of service.

  - CVE-2018-7757     Jason Yan reported a memory leak in the SAS     (Serial-Attached SCSI) subsystem. A local user on a     system with SAS devices could use this to cause a denial     of service.

  - CVE-2018-7995     Seunghun Han reported a race condition in the x86 MCE     (Machine Check Exception) driver. This is unlikely to     have any security impact.

  - CVE-2018-8781     Eyal Itkin reported that the udl (DisplayLink) driver's     mmap operation did not properly range-check the file     offset. A local user with access to a udl framebuffer     device could exploit this to overwrite kernel memory,     leading to privilege escalation.

  - CVE-2018-8822     Dr Silvio Cesare of InfoSect reported that the ncpfs     client implementation did not validate reply lengths     from the server. An ncpfs server could use this to cause     a denial of service or remote code execution in the     client.

  - CVE-2018-1000004     Luo Quan reported a race condition in the ALSA (sound)     sequencer core, between multiple ioctl operations. This     could lead to a deadlock or use-after-free. A local user     with access to a sequencer device could use this for     denial of service or possibly for privilege escalation.

  - CVE-2018-1000199     Andy Lutomirski discovered that the ptrace subsystem did     not sufficiently validate hardware breakpoint settings.
    Local users can use this to cause a denial of service,     or possibly for privilege escalation, on x86 (amd64 and     i386) and possibly other architectures.
