CVE-2026-90086

CVE-2026-90086 affects the Linux kernel AF_XDP (xsk) zero-copy TX path . The root cause is that the zero-copy path reads TX metadata whenever the UMEM has metadata space, even when the descriptor does not set the XDP_TX_METADATA flag. The fix passes descriptor options through the metadata helpers...
