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 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 state of network RNG in the Linux kernel was
potentially observable. A remote attacker could use this to expose
sensitive information. (CVE-2020-16166)
It was discovered that the NFS client implementation in the Linux kernel
did not properly perform bounds checking before copying security labels in
some situations. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2020-25212)
