USN-4440-1: linux kernel vulnerabilities It was discovered that the network block device (nbd) 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 (system crash). (CVE-2019-16089) 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 (system crash). (CVE-2019-19462) 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 (memory exhaustion). (CVE-2019-20810) Jason A. Donenfeld discovered that the ACPI implementation in the Linux kernel did not properly restrict loading SSDT code from an [ more… ]

USN-4439-1: Linux kernel vulnerabilities It was discovered that the network block device (nbd) 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 (system crash). (CVE-2019-16089) 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 (system crash). (CVE-2019-19036) 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 (system crash). (CVE-2019-19462) Chuhong Yuan discovered that go7007 USB audio device driver in the Linux kernel [ more… ]
