Summary

It was discovered that the AMD Cryptographic Coprocessor device driver in
the Linux kernel did not properly deallocate memory in some situations. A
local attacker could use this to cause a denial of service (memory
exhaustion). (CVE-2019-18808)

It was discovered that the Conexant 23885 TV card device driver for the
Linux kernel did not properly deallocate memory in some error conditions. A
local attacker could use this to cause a denial of service (memory
exhaustion). (CVE-2019-19054)

It was discovered that the ADIS16400 IIO IMU Driver for the Linux kernel
did not properly deallocate memory in certain error conditions. A local
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2019-19061)

It was discovered that the AMD Audio Coprocessor driver for the Linux
kernel did not properly deallocate memory in certain error conditions. A
local attacker with the ability to load modules could use this to cause a
denial of service (memory exhaustion). (CVE-2019-19067)

It was discovered that the Atheros HTC based wireless driver in the Linux
kernel did not properly deallocate in certain error conditions. A local
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2019-19073, CVE-2019-19074)

It was discovered that the F2FS file system in the Linux kernel did not
properly perform bounds checking in some situations, leading to an out-of-
bounds read. A local attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2019-9445)

It was discovered that the VFIO PCI driver in the Linux kernel did not
properly handle attempts to access disabled memory spaces. A local attacker
could use this to cause a denial of service (system crash).
(CVE-2020-12888)

It was discovered that the cgroup v2 subsystem in the Linux kernel did not
properly perform reference counting in some situations, leading to a NULL
pointer dereference. A local attacker could use this to cause a denial of
service or possibly gain administrative privileges. (CVE-2020-14356)

It was discovered that the state of network RNG in the Linux kernel was
potentially observable. A remote attacker could use this to expose
sensitive information. (CVE-2020-16166)
