  3. CVE-2025-21743
In the Linux kernel, the following vulnerability has been resolved: usbnet: ipheth: fix possible overflow in DPE length check Originally, it was possible for the DPE length check to overflow if wDatagramIndex + wDatagramLength > U16_MAX. This could lead to an OoB read. Move the wDatagramIndex term to the other side of the inequality. An existing condition ensures that wDatagramIndex < urb->actual_length.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usbnet: ipheth: corrige posible desbordamiento en la comprobación de longitud de DPE Originalmente, era posible que la comprobación de longitud de DPE se desbordara si wDatagramIndex + wDatagramLength &gt; U16_MAX. Esto podría provocar una lectura OoB. Mueva el término wDatagramIndex al otro lado de la desigualdad. Una condición existente asegura que wDatagramIndex &lt; urb-&gt;actual_length.
