Available for Ubuntu 19.04 (Disco Dingo), Ubuntu 18.04 LTS (Bionic Beaver), Ubuntu 16.04 LTS (Xenial Xerus), and Ubuntu 14.04 ESM (Trusty Tahr), the new Linux kernel security updates are right here to patch extra than 30 protection vulnerabilities, along with a heap buffer overflow determined in the Marvell Wireless LAN machine driver and a NULL pointer dereference determined in the Near-field communication (NFC) implementation.

The security patch additionally addresses a use-after-free vulnerability found by way of Google Project Zero's Jann Horn in the Linux kernel when getting access to LDT entries, as properly as a race condition when performing core dumps. A flaw located by way of Andrei Vlad Lutas and Dan Lutas in x86 processors, which incorrectly handled SWAPGS directions in the course of speculative execution, used to be fixed as well.

Several other security flaws affecting Linux kernel's PowerPC dlpar implementation, ptrace implementation, Bluetooth implementation, alarmtimer implementation, cleancache, USB, and block layer subsystems, MDIO bus units subsystem, Empia EM28xx DVB USB machine driver, USB video gadget class implementation, Appletalk IP encapsulation driver, as well as the XFS, Btrfs, F2FS, and HFS+ filesystems have been patched in the new security update.

If you're using Ubuntu 16.04 LTS (Xenial Xerus) with Linux kernel 4.4, you must update to linux-image 4.4.0-159.187. New kernel update released for Ubuntu are also available for Amazon Web Services (AWS) systems, Microsoft Azure Cloud systems, Google Cloud Platform (GCP) systems, Google Container Engine (GKE) systems, Oracle Cloud systems, Snapdragon processors, Raspberry Pi 2 systems, cloud environments, and OEM processors.

If you're using Ubuntu 18.04 LTS (Bionic Beaver) or Ubuntu 16.04 LTS (Xenial Xerus) with the Linux 4.15 kernel, you are urged to update your installations as soon as possible to linux-image 4.15.0-58.64. On the other hand, Ubuntu 19.04 (Disco Dingo) and Ubuntu 18.04.3 LTS (Bionic Beaver) users using the Linux 5.0 kernel are urged to update their systems to linux-image 5.0.0-25.26. source
