The security flaws vary from an information leak Linux kernel’s RDS (Reliable Datagram Sockets) implementation and a flaw in Linux kernel’s TCP implementation, to a race condition in the MIC VOP driver, a heap-based buffer overflow in the USB HID driver, and issues with the airspy USB device kernel driver. There’s also a race condition in Linux kernel’s MIC VOP driver, some bugs in the OverlayFS implementation, and issues with PowerPC platforms, affecting not only Ubuntu 16.04 LTS but also its derivatives and official flavors, including Kubuntu, Xubuntu, Lubuntu, Ubuntu MATE, Ubuntu GNOME, Ubuntu Kylin, and more.
