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 subsystem 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 blacklisted 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)");
