Description
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.
Affected configurations
• linux linux kernel (>= 2.6.34 < 6.6.136)
• linux linux kernel (>= 6.7 < 6.12.83)
• linux linux kernel (>= 6.13 < 6.18.24)
• linux linux kernel (>= 6.19 < 6.19.14)
• linux linux kernel (>= 7.0 < 7.0.1)
