    Canonical Outs Important Linux Kernel Updates For All Supported Ubuntu Releases

    Are you an Ubuntu user? Canonical has released a new batch of Linux kernel security updates for all of its supported Ubuntu Linux releases to address the latest Intel CPU vulnerabilities, as well as other important flaws. Learn more:

    As announced the other day, Canonical was quick to respond to the latest security vulnerabilities affecting Intel CPU microarchitectures, so they now published Linux kernel updates to mitigate them. These are CVE-2019-11135CVE-2018-12207CVE-2019-0154, and CVE-2019-0155, which could allow local attackers to either expose sensitive information or possibly elevate privileges or cause a denial of service.

    On top of these security issues affecting Intel CPUs, the new Linux kernel security updates also address three vulnerabilities (CVE-2019-15791CVE-2019-15792, and CVE-2019-15793) discovered by Google Project Zero's Jann Horn in the shiftfs implementation, which could allow a local attacker to either execute arbitrary code, cause a denial of service (system crash), or bypass DAC permissions.
