"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 :
- Mounting a crafted EXT4 image read-only leads to an
attacker controlled memory corruption and
SLAB-Out-of-Bounds reads.(CVE-2016-10208i1/4%0
- An issue was discovered in the hwpoison implementation
in mm/memory-failure.c in the Linux kernel before
5.0.4. When soft_offline_in_use_page() runs on a thp
tail page after pmd is split, an attacker can cause a
denial of service (BUG).(CVE-2019-10124i1/4%0
- A stack-based buffer overflow flaw was found in the
Linux kernel's early load microcode functionality. On a
system with UEFI Secure Boot enabled, a local,
privileged user could use this flaw to increase their
privileges to the kernel (ring0) level, bypassing
intended restrictions in place.(CVE-2015-2666i1/4%0
- A flaw was found in the way the Linux kernel's
networking subsystem handled offloaded packets with
multiple layers of encapsulation in the GRO (Generic
Receive Offload) code path. A remote attacker could use
this flaw to trigger unbounded recursion in the kernel
that could lead to stack corruption, resulting in a
system crash.(CVE-2016-8666i1/4%0
- The ethtool_get_wol function in net/core/ethtool.c in
the Linux kernel through 4.7, as used in Android before
2016-08-05 on Nexus 5 and 7 (2013) devices, does not
initialize a certain data structure, which allows local
users to obtain sensitive information via a crafted
application, aka Android internal bug 28803952 and
Qualcomm internal bug CR570754.(CVE-2014-9900i1/4%0
- A vulnerability was found in crypto/ahash.c in the
Linux kernel which allows attackers to cause a denial
of service (API operation calling its own callback, and
infinite recursion) by triggering EBUSY on a full
queue.(CVE-2017-7618i1/4%0
- drivers/misc/qseecom.c in the QSEECOM driver for the
Linux kernel 3.x, as used in Qualcomm Innovation Center
(QuIC) Android contributions for MSM devices and other
products, does not validate certain offset, length, and
base values within an ioctl call, which allows
attackers to gain privileges or cause a denial of
service (memory corruption) via a crafted
application.(CVE-2014-4322i1/4%0
- An integer overflow vulnerability was found in the
Linux kernel in xt_alloc_table_info, which on 32-bit
systems can lead to small structure allocation and a
copy_from_user based heap corruption.(CVE-2016-3135i1/4%0
- Stack-based buffer overflow in the
supply_lm_input_write function in
drivers/thermal/supply_lm_core.c in the MSM Thermal
driver for the Linux kernel 3.x, as used in Qualcomm
Innovation Center (QuIC) Android contributions for MSM
devices and other products, allows attackers to cause a
denial of service or possibly have unspecified other
impact via a crafted application that sends a large
amount of data through the debugfs
interface.(CVE-2016-2063i1/4%0
- The l2tp_ip_recvmsg function in net/l2tp/l2tp_ip.c in
the Linux kernel before 3.12.4 updates a certain length
value before ensuring that an associated data structure
has been initialized, which allows local users to
obtain sensitive information from kernel stack memory
via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system
call.(CVE-2013-7264i1/4%0
- A bypass was found for the Spectre v1 hardening in the
eBPF engine of the Linux kernel. The code in the
kernel/bpf/verifier.c performs undesirable
out-of-bounds speculation on pointer arithmetic in
various cases, including cases of different branches
with different state or limits to sanitize, leading to
side-channel attacks.(CVE-2019-7308i1/4%0
- The tcp_v6_syn_recv_sock function in
net/ipv6/tcp_ipv6.c in the Linux kernel mishandles
inheritance, which allows local users to cause a denial
of service or possibly have unspecified other impact
via crafted system calls, a related issue to
CVE-2017-8890. An unprivileged local user could use
this flaw to induce kernel memory corruption on the
system, leading to a crash. Due to the nature of the
flaw, privilege escalation cannot be fully ruled out,
although we believe it is unlikely.(CVE-2017-9077i1/4%0
- The cgroup offline implementation in the Linux kernel
through 4.8.11 mishandles certain drain operations,
which allows local users to cause a denial of service
(system hang) by leveraging access to a container
environment for executing a crafted application, as
demonstrated by trinity.(CVE-2016-9191i1/4%0
- The KVM implementation in the Linux kernel through
4.20.5 has a Use-after-Free.(CVE-2019-7221i1/4%0
- A NULL pointer dereference flaw was found in the way
the Linux kernel's network subsystem handled socket
creation with an invalid protocol identifier. A local
user could use this flaw to crash the
system.(CVE-2015-8543i1/4%0
- The drivers/media/usb/dvb-usb-v2/lmedm04.c in the Linux
kernel, through 4.13.11, allows local users to cause a
denial of service (general protection fault and system
crash) or possibly have unspecified other impact via a
crafted USB device, related to a missing warm-start
check and incorrect attach timing
(dm04_lme2510_frontend_attach versus
dm04_lme2510_tuner).(CVE-2017-16538i1/4%0
- A use-after-free flaw was found in the way the Linux
kernel's Advanced Linux Sound Architecture (ALSA)
implementation handled user controls. A local,
privileged user could use this flaw to crash the
system.(CVE-2014-4653i1/4%0
- A vulnerability leading to a local privilege escalation
was found in apparmor in the Linux kernel. When
proc_pid_attr_write() was changed to use memdup_user
apparmor's (interface violating) assumption that the
setprocattr buffer was always a single page was
violated.(CVE-2016-6187i1/4%0
- A vulnerability was found in the Linux kernel in
'tmpfs' file system. When file permissions are modified
via 'chmod' and the user is not in the owning group or
capable of CAP_FSETID, the setgid bit is cleared in
inode_change_ok(). Setting a POSIX ACL via 'setxattr'
sets the file permissions as well as the new ACL, but
doesn't clear the setgid bit in a similar way this
allows to bypass the check in 'chmod'.(CVE-2017-5551i1/4%0
- A flaw was found in the Linux Kernel in the
ucma_leave_multicast() function in
drivers/infiniband/core/ucma.c which allows access to a
certain data structure after freeing it in
ucma_process_join(). This allows an attacker to cause a
use-after-free bug and to induce kernel memory
corruption, leading to a system crash or other
unspecified impact. Due to the nature of the flaw,
privilege escalation cannot be fully ruled out,
although we believe it is unlikely.(CVE-2018-14734i1/4%0
