Ubuntu

Null pointer reference in some Intel(R) Graphics Drivers for Windows* before version 26.20.100.7212 and before version Linux kernel version 5.5 may allow a privileged user to potentially enable a denial of service via local access.

Weakness

A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
