CVE-2026-74559

CVE-2026-74559 affects the Linux kernel XDP/AF_XDP path. The issue arises in the xsk_build_skb() flow where, on overflow of descriptors (or invalid descriptors in fragmented packets), the generic transmit path multi-buffer handling could mishandle descriptors. The fix introduces xdp_sock::drain_c...

CVE-2026-74558

CVE-2026-74558 describes a Linux kernel vulnerability in the xsk ZC (zero-copy) batch path. The issue arises when the zero-copy Tx batch parser encounters an invalid descriptor or when a packet exceeds xdp_zc_max_segs. In these cases, descriptors can be misinterpreted, potentially advancing the T...
