USN-4525-1

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)
