Detailed vulnerability description
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists in the udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c due to integer overflow. A local attacker can gain full read and write permissions on kernel physical pages and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
