Description
A flaw was found in the Linux kernel's `sm750fb` framebuffer driver. A local user can exploit this vulnerability by providing a specially crafted input with a zero `pixclock` value via the `FBIOPUT_VSCREENINFO` ioctl. This leads to a division-by-zero error in the `ps_to_hz()` function, which can result in a system crash and a Denial of Service (DoS).
