Descriptions

In the Linux kernel, the following vulnerability has been resolved:

wifi: nl80211: Avoid address calculations via out of bounds array indexing

Before request->channels[] can be used, request->n_channels must be set.
Additionally, address calculations for memory after the "channels" array
need to be calculated from the allocation base ("request") rather than
via the first "out of bounds" index of "channels", otherwise run-time
bounds checking will throw a warning.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: nl80211: evitar cálculos de direcciones mediante indexación de matrices fuera de los límites Antes de poder utilizar request->channels[], se debe configurar request->n_channels. Además, los cálculos de direcciones para la memoria después de la matriz de "canales" deben calcularse a partir de la base de asignación ("solicitud") en lugar de mediante el primer índice "fuera de los límites" de "canales"; de lo contrario, la verificación de los límites en tiempo de ejecución arrojará un advertencia.
