Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: usb: cdc_ncm: add ndpoffset to NDP32 nframes bounds check<br />
<br />
The same bounds-check bug fixed for NDP16 in the previous patch also<br />
exists in cdc_ncm_rx_verify_ndp32(). The DPE array size is validated<br />
against the total skb length without accounting for ndpoffset, allowing<br />
out-of-bounds reads when the NDP32 is placed near the end of the NTB.<br />
<br />
Add ndpoffset to the nframes bounds check and use struct_size_t() to<br />
express the NDP-plus-DPE-array size more clearly.<br />
<br />
Compile-tested only.
