CVE-2026-23447

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.
