Descrição
In the Linux kernel, the following vulnerability has been resolved: fbdev: udlfb: avoid divide-by-zero on FBIOPUT_VSCREENINFO Much like commit 19f953e74356 (-fbdev: fb_pm2fb: Avoid potential divide by zero error-), we also need to prevent that same crash from happening in the udlfb driver as it uses pixclock directly when dividing, which will crash.
