CriticalCVSS 9.8/10Last modified Aug 17, 2026

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.
