"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: savage: Error out if pixclock equals zero\n\nThe userspace program could pass any values to the driver through\nioctl() interface. If the driver doesn't check the value of pixclock,\nit may cause divide-by-zero error.\n\nAlthough pixclock is checked in savagefb_decode_var(), but it is not\nchecked properly in savagefb_probe(). Fix this by checking whether\npixclock is zero in the function savagefb_check_var() before\ninfo->var.pixclock is used as the divisor.\n\nThis is similar to CVE-2022-3061 in i740fb which was fixed by\ncommit 15cf0b8."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fbdev: savage: error si pixclock es igual a cero. 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->var.pixclock como divisor. Esto es similar a CVE-2022-3061 en i740fb que se solucion\u00f3 mediante el commit 15cf0b8."
