Intel has issued fixes for five high-severity vulnerabilities in its graphics drivers.
Intel develops graphics drivers for Windows OS to communicate with specific Intel graphics devices, for instance.
The most serious of the flaws in Intel's graphics drivers, which ranks 8.8 out of 10 on the CVSS scale, stems from the kernel mode driver, which is the piece of a graphics driver that executes any instruction it needs on the CPU without waiting, and can reference any memory address that is available.
Another privilege-escalation issue stemming from insufficient control-flow management was fixed in Intel graphics drivers.
One of these flaws is a buffer-overflow issue in the Baseboard Management Controller firmware for some Intel server boards, server systems and compute modules.
"Improper buffer restrictions in firmware for Intel 7360 Cell Modem before UDE version 9.4.370 may allow unauthenticated users to potentially enable denial-of-service via network access," said Intel.
