    Details:
    
    It was discovered that the Intel Wi-Fi device driver in the Linux kernel
    did not properly validate certain Tunneled Direct Link Setup (TDLS). A
    physically proximate attacker could use this to cause a denial of service
    (Wi-Fi disconnect). (CVE-2019-0136)
    
    It was discovered that the Bluetooth UART implementation in the Linux
    kernel did not properly check for missing tty operations. A local attacker
    could use this to cause a denial of service. (CVE-2019-10207)
    
    It was discovered that the GTCO tablet input driver in the Linux kernel did
    not properly bounds check the initial HID report sent by the device. A
    physically proximate attacker could use this to cause a denial of service
    (system crash) or possibly execute arbitrary code. (CVE-2019-13631)
    
    It was discovered that an out-of-bounds read existed in the QLogic QEDI
    iSCSI Initiator Driver in the Linux kernel. A local attacker could possibly
    use this to expose sensitive information (kernel memory). (CVE-2019-15090)
    
    Hui Peng and Mathias Payer discovered that the USB audio driver for the
    Linux kernel did not properly validate device meta data. A physically
    proximate attacker could use this to cause a denial of service (system
    crash). (CVE-2019-15117)
    
    Hui Peng and Mathias Payer discovered that the USB audio driver for the
    Linux kernel improperly performed recursion while handling device meta
    data. A physically proximate attacker could use this to cause a denial of
    service (system crash). (CVE-2019-15118)
    
    It was discovered that the Raremono AM/FM/SW radio device driver in the
    Linux kernel did not properly allocate memory, leading to a use-after-free.
    A physically proximate attacker could use this to cause a denial of service
    or possibly execute arbitrary code. (CVE-2019-15211)
    
    It was discovered at a double-free error existed in the USB Rio 500 device
    driver for the Linux kernel. A physically proximate attacker could use this
    to cause a denial of service. (CVE-2019-15212)
    
    It was discovered that a race condition existed in the CPiA2 video4linux
    device driver for the Linux kernel, leading to a use-after-free. A
    physically proximate attacker could use this to cause a denial of service
    (system crash) or possibly execute arbitrary code. (CVE-2019-15215)
    
    It was discovered that a race condition existed in the Softmac USB Prism54
    device driver in the Linux kernel. A physically proximate attacker could
    use this to cause a denial of service (system crash). (CVE-2019-15220)
    
    Benjamin Moody discovered that the XFS file system in the Linux kernel did
    not properly handle an error condition when out of disk quota. A local
    attacker could possibly use this to cause a denial of service.
    (CVE-2019-15538)
    
    It was discovered that the Hisilicon HNS3 ethernet device driver in the
    Linux kernel contained an out of bounds access vulnerability. A local
    attacker could use this to possibly cause a denial of service (system
    crash). (CVE-2019-15925)
    
    It was discovered that the Atheros mobile chipset driver in the Linux
    kernel did not properly validate data in some situations. An attacker could
    use this to cause a denial of service (system crash). (CVE-2019-15926)
    
    Daniele Antonioli, Nils Ole Tippenhauer, and Kasper B. Rasmussen discovered
    that the Bluetooth protocol BR/EDR specification did not properly require
    sufficiently strong encryption key lengths. A physically proximate attacker
    could use this to expose sensitive information. (CVE-2019-9506)
    
    It was discovered that ZR364XX Camera USB device driver for the Linux
    kernel did not properly initialize memory. A physically proximate attacker
    could use this to cause a denial of service (system crash).
    (CVE-2019-15217)
    
    It was discovered that the Siano USB MDTV receiver device driver in the
    Linux kernel made improper assumptions about the device characteristics. A
    physically proximate attacker could use this cause a denial of service
    (system crash). (CVE-2019-15218)
    
    It was discovered that the Line 6 POD USB device driver in the Linux kernel
    did not properly validate data size information from the device. A
    physically proximate attacker could use this to cause a denial of service
    (system crash). (CVE-2019-15221)
    
    It was discovered that the Line 6 USB driver for the Linux kernel contained
    a race condition when the device was disconnected. A physically proximate
    attacker could use this to cause a denial of service (system crash).
    (CVE-2019-15223)

    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.
