    service (system crash) or execute arbitrary code. (CVE-2019-19524)
    
    It was discovered that the NXP PN533 NFC USB driver in the Linux kernel did
    not properly free resources after a late probe error, leading to a use-
    after-free vulnerability. A physically proximate attacker could use this to

    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.
