CVE-2026-72399
net: enetc: check the number of BDs needed for xdp_frame
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: net: enetc: check the number of BDs needed for xdp_frame The size of xdp_redirect_arr array is ENETC_MAX_SKB_FRAGS. However, the number of fragments contained in xdp_frame may be greater than or equal to ENETC_MAX_SKB_FRAGS, which will cause the access to xdp_redirect_arr to be out of bounds.
