781209adb64b9fdfd3531ac239587a48ffe64dfe0b18666338bdf00c5b3eba1cUbuntu Security Notice 4440-1 - It was discovered that the network block device implementation in the Linux kernel did not properly check for error conditions in some situations. An attacker could possibly use this to cause a denial of service. It was discovered that the kernel->user space relay implementation in the Linux kernel did not properly check return values in some situations. A local attacker could possibly use this to cause a denial of service. Various other issues were also addressed.
93050dd9768e16bf8e7459dcfcb358a4a7847e519f51bfbd8b25246f475d27e4Ubuntu Security Notice 4439-1 - It was discovered that the network block device implementation in the Linux kernel did not properly check for error conditions in some situations. An attacker could possibly use this to cause a denial of service. It was discovered that the btrfs file system implementation in the Linux kernel did not properly validate file system metadata in some situations. An attacker could use this to construct a malicious btrfs image that, when mounted, could cause a denial of service. Various other issues were also addressed.
789e8f002f0de81a8d353f1ea8d5a4ecb5aa606f09d0d78851c94acd0cbcd044Ubuntu Security Notice 4427-1 - It was discovered that the Kvaser CAN/USB driver in the Linux kernel did not properly initialize memory in certain situations. A local attacker could possibly use this to expose sensitive information. Chuhong Yuan discovered that go7007 USB audio device driver in the Linux kernel did not properly deallocate memory in some failure conditions. A physically proximate attacker could use this to cause a denial of service. Various other issues were also addressed.
b977bb1eef5006f04c02310b64f67dfc0df0cf66bdb9c9980f831579b1b67812Ubuntu Security Notice 4426-1 - Jason A. Donenfeld discovered that the ACPI implementation in the Linux kernel did not properly restrict loading SSDT code from an EFI variable. A privileged attacker could use this to bypass Secure Boot lockdown restrictions and execute arbitrary code in the kernel. Fan Yang discovered that the mremap implementation in the Linux kernel did not properly handle DAX Huge Pages. A local attacker with access to DAX storage could use this to gain administrative privileges. Various other issues were also addressed.
