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:
Asannouncedthe 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 areCVE-2019-11135,CVE-2018-12207,CVE-2019-0154, andCVE-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-2019-15791,CVE-2019-15792, andCVE-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.
