[USN-4157-1] Linux kernel vulnerabilities

Severity Critical
Affected Packages 20
CVEs 9

Several security issues were fixed in the Linux kernel.

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)
