may lead to a privilege escalation, denial of service or information
leaks.

CVE-2019-2182

Hanjun Guo and Lei Li reported a race condition in the arm64
virtual memory management code, which could lead to an information
disclosure, denial of service (crash), or possibly privilege
escalation.

CVE-2019-5108

Mitchell Frank of Cisco discovered that when the IEEE 802.11
(WiFi) stack was used in AP mode with roaming, it would trigger
roaming for a newly associated station before the station was
authenticated. An attacker within range of the AP could use this
to cause a denial of service, either by filling up a switching
table or by redirecting traffic away from other stations.

CVE-2019-19319

Jungyeon discovered that a crafted filesystem can cause the ext4
implementation to deallocate or reallocate journal blocks. A user
permitted to mount filesystems could use this to cause a denial of
service (crash), or possibly for privilege escalation.

CVE-2019-19462

The syzbot tool found a missing error check in the 'relay'
library used to implement various files under debugfs. A local
user permitted to access debugfs could use this to cause a denial
of service (crash) or possibly for privilege escalation.

CVE-2019-19768

Tristan Madani reported a race condition in the blktrace debug
facility that could result in a use-after-free. A local user able
to trigger removal of block devices could possibly use this to
cause a denial of service (crash) or for privilege escalation.

CVE-2019-20806

A potential null pointer dereference was discovered in the tw5864
media driver. The security impact of this is unclear.

CVE-2019-20811

The Hulk Robot tool found a reference-counting bug in an error
path in the network subsystem. The security impact of this is
unclear.

CVE-2020-0543

Researchers at VU Amsterdam discovered that on some Intel CPUs
supporting the RDRAND and RDSEED instructions, part of a random
value generated by these instructions may be used in a later
speculative execution on any core of the same physical CPU.
Depending on how these instructions are used by applications, a
local user or VM guest could use this to obtain sensitive
information such as cryptographic keys from other users or VMs.

This vulnerability can be mitigated by a microcode update, either
as part of system firmware (BIOS) or through the intel-microcode
package in Debian's non-free archive section. This kernel update
only provides reporting of the vulnerability and the option to
disable the mitigation if it is not needed.

CVE-2020-2732

Paulo Bonzini discovered that the KVM implemen ...
