What is CVE-2022-2085?

A NULL pointer dereference vulnerability exists in the Ghostscript rendering engine, which can be triggered when processing image data with more than 64 bits per pixel. This vulnerability occurs due to a missing init_device_procs for the mem_x_device, leading to a crash of the application when a large number of bits are allocated in memory.
