Details

Asaf Modelevsky discovered that the Intel® 10GbE PCI Express (ixgbe)
Ethernet driver for the Linux kernel performed insufficient control flow
management. A local attacker could possibly use this to cause a denial of
service. (CVE-2021-33061)

It was discovered that the virtual terminal driver in the Linux kernel did
not properly handle VGA console font changes, leading to an out-of-bounds
write. A local attacker could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2021-33656)
