[USN-4300-1] Linux kernel vulnerabilities

Severity Medium
Affected Packages 43
CVEs 11
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

It was discovered that the KVM implementation in the Linux kernel, when
paravirtual TLB flushes are enabled in guests, the hypervisor in some
situations could miss deferred TLB flushes or otherwise mishandle them. An
attacker in a guest VM could use this to expose sensitive information (read
memory from another guest VM). (CVE-2019-3016)

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)

It was discovered that the Afatech AF9005 DVB-T USB 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-2019-18809)

It was discovered that the Intel(R) XL710 Ethernet Controller 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-2019-19043)

It was discovered that the RPMSG character device interface 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-2019-19053)

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,
CVE-2019-19059)

It was discovered that the Serial Peripheral Interface (SPI) 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-2019-19064)

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)
