CVE-2026-31618

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