Linux kernel vulnerabilities

Description

## Releases * Ubuntu 19.04 ## Packages * linux \- Linux kernel * linux-aws \- Linux kernel for Amazon Web Services (AWS) systems * linux-azure \- Linux kernel for Microsoft Azure Cloud systems * linux-gcp \- Linux kernel for Google Cloud Platform (GCP) systems * linux-kvm \- Linux kernel for cloud environments * linux-raspi2 \- Linux kernel for Raspberry Pi 2 * linux-snapdragon \- Linux kernel for Snapdragon processors Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14814, CVE-2019-14815, CVE-2019-14816) Matt Delco discovered that the KVM hypervisor implementation in the Linux kernel did not properly perform bounds checking when handling coalesced MMIO write operations. A local attacker with write access to /dev/kvm could use this to cause a denial of service (system crash). (CVE-2019-14821) Hui Peng and Mathias Payer discovered that the 91x Wi-Fi driver in the Linux kernel did not properly handle error conditions on initialization, leading to a double-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2019-15504) It was discovered that the Technisat DVB-S/S2 USB device driver in the Linux kernel contained a buffer overread. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2019-15505) Brad Spengler discovered that a Spectre mitigation was improperly implemented in the ptrace susbsystem of the Linux kernel. A local attacker could possibly use this to expose sensitive information. (CVE-2019-15902) It was discovered that the IPv6 RDS implementation in the Linux kernel did not properly initialize fields in a data structure returned to user space. A local attacker could use this to expose sensitive information (kernel memory). Please note that the RDS protocol is disabled via blocklist in Ubuntu by default. (CVE-2019-16714) It was discovered that an integer overflow existed in the Binder implementation of the Linux kernel, leading to a buffer overflow. A local attacker could use this to escalate privileges. (CVE-2019-2181)
