Summary
In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix out of bounds reads when finding clock sources The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check.

Para solucionarlo, este parche agrega controles de cordura a las funciones de validaci\u00f3n para el recorrido del descriptor de reloj. Cuando la longitud del descriptor es m\u00e1s corta de lo esperado, se omite en el bucle. Para los descriptores de fuente de reloj y multiplicador de reloj, podemos comparar bLength con el sizeof() de cada tipo de descriptor. OTOH, el descriptor del selector de reloj de UAC2 y UAC3 tiene una matriz de elementos bNrInPins y dos campos m\u00e1s en su cola, por lo que deben verificarse adem\u00e1s de la verificaci\u00f3n sizeof()."
