 ---------- Forwarded message ---------

From: Steve Beattie <steve.beattie@canonical.com>

Date: Sep 2, 2020 12:11PM

Timothy Michaud discovered that the i915 graphics driver in the Linux

kernel did not properly validate user memory locations for the

i915_gem_execbuffer2_ioctl. A local attacker could possibly use this to

cause a denial of service or execute arbitrary code. (CVE-2018-20669)

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 (kernel memory).

(CVE-2019-19947)

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)

It was discovered that the elf handling code in the Linux kernel did not

initialize memory before using it in certain situations. A local attacker

could use this to possibly expose sensitive information (kernel memory).

(CVE-2020-10732)

It was discovered that the Linux kernel did not correctly apply Speculative

Store Bypass Disable (SSBD) mitigations in certain situations. A local

attacker could possibly use this to expose sensitive information.

(CVE-2020-10766)

It was discovered that the Linux kernel did not correctly apply Indirect

Branch Predictor Barrier (IBPB) mitigations in certain situations. A local

attacker could possibly use this to expose sensitive information.

(CVE-2020-10767)

It was discovered that the Linux kernel could incorrectly enable Indirect

Branch Speculation after it has been disabled for a process via a prctl()

call. A local attacker could possibly use this to expose sensitive

information. (CVE-2020-10768)

Luca Bruno discovered that the zram module in the Linux kernel did not

properly restrict unprivileged users from accessing the hot_add sysfs file.

A local attacker could use this to cause a denial of service (memory

exhaustion). (CVE-2020-10781)

It was discovered that the XFS file system implementation in the Linux

kernel did not properly validate meta data in some circumstances. An

attacker could use this to construct a malicious XFS image that, when

mounted, could cause a denial of service. (CVE-2020-12655)

It was discovered that the bcache subsystem in the Linux kernel did not

properly release a lock in some error conditions. A local attacker could

possibly use this to cause a denial of service. (CVE-2020-12771)

kernel contained an integer overflow. A local attacker could possibly use

this to have an unspecified impact. (CVE-2020-13974)

Kyungtae Kim discovered that the USB testing driver in the Linux kernel did

not properly deallocate memory on disconnect events. A physically proximate

attacker could use this to cause a denial of service (memory exhaustion).

(CVE-2020-15393)

It was discovered that the NFS server implementation in the Linux kernel

did not properly honor umask settings when setting permissions while

creating file system objects if the underlying file system did not support

ACLs. An attacker could possibly use this to expose sensitive information

or violate system integrity. (CVE-2020-24394)

It was discovered that the Kerberos SUNRPC GSS implementation in the Linux

kernel did not properly deallocate memory on module unload. A local

privileged attacker could possibly use this to cause a denial of service

(memory exhaustion). (CVE-2020-12656)

FSF: Meet the star witness: Your "smart" speaker

From August 23rd by Sidney Fussell

Not controlling the software you run on your smart device gives new meaning to the phrase "everything you say can be used against you." In this article, we learn about the frightening upswing in use of these devices in police investigations. Remember, if you don't control your devices, they can be used to control you, and the smartest thing you can do with "smart" devices is avoid them!
