TITLE

Windows  and  Linux  for  Intel(R) Graphics Drivers  Integer overflow vulnerability in

DESCRIPTION

Integer overflow in the firmware for some Intel(R) Graphics Drivers for Windows * before version 26.20.100.7212 and before Linux kernel version 5.5 may allow a privileged user to potentially enable an escalation of privilege via local access. There is a security vulnerability in Intel Graphics Drivers. There is no information about this vulnerability at present. Please pay attention to CNNVD or manufacturer announcements at any time.
