  - A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap     flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB)     being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate     their privileges inside the guest. Linux guests are not affected by this. (CVE-2017-7518)

  - The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers     to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c,     fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (CVE-2017-7645)

  - Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with     dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel     heap pages to the userspace. This has been fixed upstream in     https://github.com/torvalds/linux/commit/a45b599ad808c3c982fdcdc12b0b8611c2f92824 already. The problem has     limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the     Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties     dispute the relevance of this report, noting that the requirement for an attacker to have both the     CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it virtually impossible to exploit. (CVE-2018-1000204)

  - drivers/scsi/libsas/sas_scsi_host.c in the Linux kernel before 4.16 allows local users to cause a denial     of service (ata qc leak) by triggering certain failure conditions. NOTE: a third party disputes the     relevance of this report because the failure can only occur for physically proximate attackers who unplug     SAS Host Bus Adapter cables (CVE-2018-10021)

  - The kernel_wait4 function in kernel/exit.c in the Linux kernel before 4.13, when an unspecified     architecture and compiler is used, might allow local users to cause a denial of service by triggering an     attempted use of the -INT_MIN value. (CVE-2018-10087)

  - The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified     architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN     argument. (CVE-2018-10124)

  - The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3     allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted     xfs image. (CVE-2018-10323)

  - The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to     cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system     calls. (CVE-2018-10675)

  - 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)

  - A flaw was found in the Linux kernel's ext4 filesystem. A local user can cause an out-of-bound access in     ext4_get_group_info function, a denial of service, and a system crash by mounting and operating on a     crafted ext4 filesystem image. (CVE-2018-10881)

  - The ext4_iget function in fs/ext4/inode.c in the Linux kernel through 4.15.15 mishandles the case of a     root directory with a zero i_links_count, which allows attackers to cause a denial of service     (ext4_process_freed_data NULL pointer dereference and OOPS) via a crafted ext4 image. (CVE-2018-1092)

  - The ext4_valid_block_bitmap function in fs/ext4/balloc.c in the Linux kernel through 4.15.15 allows     attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image     because balloc.c and ialloc.c do not validate bitmap block numbers. (CVE-2018-1093)

  - 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-2018-10940)

  - 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-2018-12233)

  - An issue was discovered in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel through 4.17.3. An OOPS may     occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp. (CVE-2018-13094)

  - The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create     files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and     is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a     plain file whose group ownership is that group. The intended behavior was that the non-member can trigger     creation of a directory (but not a plain file) whose group ownership is that group. The non-member can     escalate privileges by making the plain file executable and SGID. (CVE-2018-13405)

  - An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c in the Linux kernel     before 4.17.4 could result in local attackers being able to crash the kernel or potentially elevate     privileges because kmalloc_array is not used. (CVE-2018-13406)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
