Description OSIDB Bzimport 2026-08-15 06:23:39 UTC 
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.
