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 offset2lib patch as used in the Linux Kernel contains a vulnerability that allows a PIE binary to be execve()'ed with 1GB of arguments or environmental strings then the stack occupies the address 0x80000000 and the PIE binary is mapped above 0x40000000 nullifying the protection of the offset2lib patch. This affects Linux Kernel version 4.11.5 and earlier. This is a different issue than CVE-2017-1000371. This issue appears to be limited to i386 based systems.(CVE-2017-1000370i1/4%0

  • Integer overflow in the LZ4 algorithm implementation, as used in Yann Collet LZ4 before r118 and in the lz4_uncompress function in lib/lz4/lz4_decompress.c in the Linux kernel before 3.15.2, on 32-bit platforms might allow context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted Literal Run that would be improperly handled by programs not complying with an API limitation, a different vulnerability than CVE-2014-4715.(CVE-2014-4611i1/4%0

  • The replace_map_fd_with_map_ptr function in kernel/bpf/verifier.c in the Linux kernel before 4.5.5 does not properly maintain an fd data structure, which allows local users to gain privileges or cause a denial of service (use-after-free) via crafted BPF instructions that reference an incorrect file descriptor.(CVE-2016-4557i1/4%0

  • The usb_destroy_configuration() function, in ‘drivers/usb/core/config.c’ in the USB core subsystem, in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources. This allows local users to cause a denial of service, due to out-of-bounds write access, or possibly have unspecified other impact via a crafted USB device. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2017-17558i1/4%0

  • The cdrom_ioctl_media_changed function in drivers/cdrom/cdrom.c in the Linux kernel before 4.16.6 allows local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory.(CVE-2018-10940i1/4%0

  • It was found that the parse_rock_ridge_inode_internal() function of the Linux kernel’s ISOFS implementation did not correctly check relocated directories when processing Rock Ridge child link (CL) tags. An attacker with physical access to the system could use a specially crafted ISO image to crash the system or, potentially, escalate their privileges on the system.(CVE-2014-5471i1/4%0

  • A flaw was found in the Linux kernel’s implementation of Unix sockets. A server polling for client-socket data could put the peer socket on a wait list the peer socket could then close the connection, making the reference on the wait list no longer valid. This could lead to bypassing the permissions on a Unix socket and packets being injected into the stream, and could also panic the machine (denial of service).(CVE-2013-7446i1/4%0

  • The do_check function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allows local users to obtain sensitive address information via crafted bpf system calls.(CVE-2017-9150i1/4%0

  • The WLAN (aka Wi-Fi) driver for the Linux kernel 3.x and 4.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not verify authorization for private SET IOCTL calls, which allows attackers to gain privileges via a crafted application, related to wlan_hdd_hostapd.c and wlan_hdd_wext.c.(CVE-2015-0571i1/4%0

  • arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes.(CVE-2018-18021i1/4%0

  • A resource-exhaustion vulnerability was found in the kernel, where an unprivileged process could allocate and accumulate far more file descriptors than the process’ limit. A local, unauthenticated user could exploit this flaw by sending file descriptors over a Unix socket and then closing them to keep the process’ fd count low, thereby creating kernel-memory or file-descriptors exhaustion (denial of service).(CVE-2016-2550i1/4%0

  • The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data structures have 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, related to net/ipv4/ping.c, net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c.(CVE-2013-7263i1/4%0

  • It is possible for a single process to cause an OOM condition by filling large pipes with data that are never read. A typical process filling 4096 pipes with 1 MB of data will use 4 GB of memory and there can be multiple such processes, up to a per-user-limit.(CVE-2016-2847i1/4%0

  • The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call.(CVE-2016-9178i1/4%0

  • It was found that the x86 ISA (Instruction Set Architecture) is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way (sequential) delivering of benign exceptions such as #DB (debug exception) is handled. A privileged user inside a guest could use this flaw to create denial of service conditions on the host kernel.(CVE-2015-8104i1/4%0

  • The Direct Rendering Manager (DRM) subsystem in the Linux kernel through 4.x mishandles requests for Graphics Execution Manager (GEM) objects, which allows context-dependent attackers to cause a denial of service (memory consumption) via an application that processes graphics data, as demonstrated by JavaScript code that creates many CANVAS elements for rendering by Chrome or Firefox.(CVE-2013-7445i1/4%0

  • A flaw was found in the Linux kernel which does not initialize certain data structures used by DMA transfer on ARM64 based systems. This could allow local users to obtain sensitive information from kernel memory by triggering a dma_mmap call and reconstructing the data.(CVE-2015-8950i1/4%0

  • A race condition was found in the Linux kernel before version 4.11-rc1 in ‘fs/timerfd.c’ file which allows a local user to cause a kernel list corruption or use-after-free via simultaneous operations with a file descriptor which leverage improper ‘might_cancel’ queuing. An unprivileged local user could use this flaw to cause a denial of service of the system. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2017-10661i1/4%0

  • The sg_ioctl() function in ‘drivers/scsi/sg.c’ in the Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows local users to obtain sensitive information from uninitialized kernel heap-memory locations via an SG_GET_REQUEST_TABLE ioctl call for ‘/dev/sg0’.(CVE-2017-14991i1/4%0

  • A race condition in the ip4_datagram_release_cb function in net/ipv4/datagram.c in the Linux kernel allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging incorrect expectations about locking during multithreaded access to internal data structures for IPv4 UDP sockets.(CVE-2014-9914i1/4%0
