Software afectado LINUX KERNEL
 
In the Linux kernel, the following vulnerability has been resolved:

fbcon: check return value of con2fb_acquire_newinfo()

If fbcon_open() fails when called from con2fb_acquire_newinfo() then
info->fbcon_par pointer remains NULL which is later dereferenced.

Add check for return value of the function con2fb_acquire_newinfo() to
avoid it.
