Title
fbdev: savage: Error out if pixclock equals zero
Summary
In the Linux kernel, the following vulnerability has been resolved: fbdev: savage: Error out if pixclock equals zero The userspace program could pass any values to the driver through ioctl() interface. If the driver doesn't check the value of pixclock, it may cause divide-by-zero error. Although pixclock is checked in savagefb_decode_var(), but it is not checked properly in savagefb_probe(). Fix this by checking whether pixclock is zero in the function savagefb_check_var() before info->var.pixclock is used as the divisor. This is similar to CVE-2022-3061 in i740fb which was fixed by commit 15cf0b8.

El programa de espacio de usuario podr\u00eda pasar cualquier valor al controlador a trav\u00e9s de la interfaz ioctl(). Si el controlador no verifica el valor de pixclock, puede causar un error de divisi\u00f3n por cero. Aunque pixclock est\u00e1 marcado en savagefb_decode_var(), no est\u00e1 marcado correctamente en savagefb_probe(). Solucione este problema verificando si pixclock es cero en la funci\u00f3n savagefb_check_var() antes de usar info-\u0026gt;var.pixclock como divisor. Esto es similar a CVE-2022-3061 en i740fb que se solucion\u00f3 mediante el commit 15cf0b8."
