Summary
linux-oem-5.14 vulnerabilities
Details

Asaf Modelevsky discovered that the Intel(R) 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 framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, 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-2021-33655)
