USN-4681-1: Linux kernel vulnerabilities<\/p>\n
Ryan Hall discovered that the Intel 700 Series Ethernet Controllers driver
\nin the Linux kernel did not properly deallocate memory in some conditions.
\nA local attacker could use this to cause a denial of service (kernel memory
\nexhaustion). (CVE-2019-0148)<\/p>\n
It was discovered that the console keyboard driver in the Linux kernel
\ncontained a race condition. A local attacker could use this to expose
\nsensitive information (kernel memory). (CVE-2020-25656)<\/p>\n
Minh Yuan discovered that the tty driver in the Linux kernel contained race
\nconditions when handling fonts. A local attacker could possibly use this to
\nexpose sensitive information (kernel memory). (CVE-2020-25668)<\/p>\n
Jinoh Kang discovered that the Xen event channel infrastructure in the
\nLinux kernel contained a race condition. An attacker in guest could
\npossibly use this to cause a denial of service (dom0 crash).

Minh Yuan discovered that the framebuffer console driver in the Linux
\nkernel did not properly handle fonts in some conditions. A local attacker
\ncould use this to cause a denial of service (system crash) or possibly
\nexpose sensitive information (kernel memory). (CVE-2020-28974)<\/p>\n
