Summary

The BPF subsystem in the Linux kernel before 4.5.5 mishandles reference counts, which allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted application on (1) a system with more than 32 Gb of memory, related to the program reference count or (2) a 1 Tb system, related to the map reference count.

    "Justin Yackoski discovered that the Atheros L2 Ethernet Driver in the
    Linux kernel incorrectly enables scatter/gather I/O. A remote attacker
    could use this to obtain potentially sensitive information from kernel
    memory. (CVE-2016-2117)
    
    Jann Horn discovered that eCryptfs improperly attempted to use the
    mmap() handler of a lower filesystem that did not implement one,
    causing a recursive page fault to occur. A local unprivileged attacker
    could use to cause a denial of service (system crash) or possibly
    execute arbitrary code with administrative privileges. (CVE-2016-1583)
    
    Multiple race conditions where discovered in the Linux kernel's ext4
    file system. A local user could exploit this flaw to cause a denial of
    service (disk corruption) by writing to a page that is associated with
    a different users file after unsynchronized hole punching and
    page-fault handling. (CVE-2015-8839)
    
    Ralf Spenneberg discovered that the Linux kernel's GTCO digitizer USB
    device driver did not properly validate endpoint descriptors. An
    attacker with physical access could use this to cause a denial of
    service (system crash). (CVE-2016-2187)
    
    Vitaly Kuznetsov discovered that the Linux kernel did not properly
    suppress hugetlbfs support in X86 paravirtualized guests. An attacker
    in the guest OS could cause a denial of service (guest system crash).
    (CVE-2016-3961)
    
    Kangjie Lu discovered an information leak in the ANSI/IEEE 802.2 LLC
    type 2 Support implementations in the Linux kernel. A local attacker
    could use this to obtain potentially sensitive information from kernel
    memory. (CVE-2016-4485)
    
    Kangjie Lu discovered an information leak in the routing netlink
    socket interface (rtnetlink) implementation in the Linux kernel. A
    local attacker could use this to obtain potentially sensitive
    information from kernel memory. (CVE-2016-4486)
    
    Jann Horn discovered that the extended Berkeley Packet Filter (eBPF)
    implementation in the Linux kernel could overflow reference counters
    on systems with more than 32GB of physical ram and with RLIMIT_MEMLOCK
    set to infinite. A local unprivileged attacker could use to create a
    use-after- free situation, causing a denial of service (system crash)
    or possibly gain administrative privileges. (CVE-2016-4558)
    
    Jann Horn discovered that the InfiniBand interfaces within the Linux
    kernel could be coerced into overwriting kernel memory. A local
    unprivileged attacker could use this to possibly gain administrative
    privileges on systems where InifiniBand related kernel modules are
    loaded. (CVE-2016-4565)
    
    It was discovered that in some situations the Linux kernel did not
    handle propagated mounts correctly. A local unprivileged attacker
    could use this to cause a denial of service (system crash).
    (CVE-2016-4581).

    descriptionAccording 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 : - In the ea_get function in fs/jfs/xattr.c in the Linux kernel through 4.17.1, a memory corruption bug in JFS can be triggered by calling setxattr twice with two different extended attribute names on the same file. This vulnerability can be triggered by an unprivileged user with the ability to create files and execute programs. A kmalloc call is incorrect, leading to slab-out-of-bounds in jfs_xattr.(CVE-2018-12233i1/4%0 - The spectre_v2_select_mitigation function in arch/x86/kernel/cpu/bugs.c in the Linux kernel before 4.18.1 does not always fill RSB upon a context switch, which makes it easier for attackers to conduct userspace-userspace spectreRSB attacks.(CVE-2018-15572i1/4%0 - Race condition in the queue_delete function in sound/core/seq/seq_queue.c in the Linux kernel before 4.4.1 allows local users to cause a denial of service (use-after-free and system crash) by making an ioctl call at a certain time.(CVE-2016-2544i1/4%0 - A flaw was found in the Linux kernel
