[USN-4525-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 67
CVEs 5
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

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)
