Vulnerability Insight:
Paulo Bonzini discovered that the KVM hypervisor implementation in the
Linux kernel could improperly let a nested (level 2) guest access the
resources of a parent (level 1) guest in certain situations. An attacker
could use this to expose sensitive information. (CVE-2020-2732)
Gregory Herrero discovered that the fix for CVE-2019-14615 to address the
Linux kernel not properly clearing data structures on context switches for
certain Intel graphics processors was incomplete. A local attacker could
use this to expose sensitive information. (CVE-2020-8832)
It was discovered that the IPMI message handler implementation in the Linux
kernel did not properly deallocate memory in certain situations. A local
attacker could use this to cause a denial of service (kernel memory
exhaustion). (CVE-2019-19046)
It was discovered that the Intel WiMAX 2400 driver in the Linux kernel did
not properly deallocate memory in certain situations. A local attacker
could use this to cause a denial of service (kernel memory exhaustion).
(CVE-2019-19051)
It was discovered that the Marvell Wi-Fi device driver in the Linux kernel
did not properly deallocate memory in certain error conditions. A local
attacker could use this to possibly cause a denial of service (kernel
memory exhaustion). (CVE-2019-19056)
It was discovered that the Intel(R) Wi-Fi device driver in the Linux kernel
device driver in the Linux kernel did not properly deallocate memory in
certain error conditions. A local attacker could possibly use this to cause
a denial of service (kernel memory exhaustion). (CVE-2019-19058)
It was discovered that the Brocade BFA Fibre Channel device driver in the
Linux kernel did not properly deallocate memory in certain error
conditions. A local attacker could possibly use this to cause a denial of
service (kernel memory exhaustion). (CVE-2019-19066)
It was discovered that the Realtek RTL8xxx USB Wi-Fi device driver in the
Linux kernel did not properly deallocate memory in certain error
conditions. A local attacker could possibly use this to cause a denial of
service (kernel memory exhaustion). (CVE-2019-19068)
It was discovered that ZR364XX Camera USB device driver for the Linux
kernel did not properly initialize memory. A physically proximate attacker
could use this to cause a denial of service (system crash).
(CVE-2019-15217)
