CVE-2025-38483

In the Linux kernel, the following vulnerability has been resolved: comedi: das16m1: Fix bit shift out of bounds When checking for a supported IRQ number, the following test is used: /* only irqs 2, 3, 4, 5, 6, 7, 10, 11, 12, 14, and 15 are valid */ if ((1 << it->options[1]) & 0xdcfc) { However, `it->options[i]` is an unchecked `int` value from userspace, so the shift amount could be negative or out of bounds. Fix the test by requiring `it->options[1]` to be within bounds before proceeding with the original test.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: comedi: das16m1: Corregir desplazamiento de bits fuera de los límites Al comprobar un número de IRQ compatible, se utiliza la siguiente prueba: /* solo las irq 2, 3, 4, 5, 6, 7, 10, 11, 12, 14 y 15 son válidas */ if ((1 &lt;&lt; it-&gt;options[1]) &amp; 0xdcfc) { Sin embargo, `it-&gt;options[i]` es un valor `int` sin comprobar del espacio de usuario, por lo que la cantidad de desplazamiento podría ser negativa o estar fuera de los límites. Corrija la prueba exigiendo que `it-&gt;options[1]` esté dentro de los límites antes de continuar con la prueba original.
