    Details:
    
    USN 4115-1 fixed vulnerabilities in the Linux 4.15 kernel for Ubuntu
    18.04 LTS and Ubuntu 16.04 LTS. Unfortunately, as part of the update,
    a regression was introduced that caused a kernel crash when handling
    fragmented packets in some situations. This update addresses the issue.
    
    We apologize for the inconvenience.
    
    Original advisory details:
    
     Hui Peng and Mathias Payer discovered that the Option USB High Speed driver

     sent signals in some situations on PowerPC systems with transactional
     memory disabled. A local attacker could use this to cause a denial of
     service. (CVE-2019-13648)
    
     It was discovered that the floppy driver in the Linux kernel did not
     properly validate meta data, leading to a buffer overread. A local attacker
     could use this to cause a denial of service (system crash).
     (CVE-2019-14283)
    
     It was discovered that the floppy driver in the Linux kernel did not
     properly validate ioctl() calls, leading to a division-by-zero. A local
     attacker could use this to cause a denial of service (system crash).
     (CVE-2019-14284)
    
     Tuba Yavuz discovered that a race condition existed in the DesignWare USB3
     DRD Controller device driver in the Linux kernel. A physically proximate

    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed.
    Unless you manually uninstalled the standard kernel metapackages
    (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
    linux-powerpc), a standard system upgrade will automatically perform
    this as well.
