CVE-2024-26853Public exploitNetwork attack vector

Remote kernel panic via double-returned XDP frame

Published Apr 17, 2024 · Updated Aug 5, 2026

Memory corruption in affected Linux kernels allows remote attackers to trigger a kernel panic via traffic redirected to an Intel i225 NIC. The igc_xdp_xmit function releases a failed frame through xdp_return_frame_rx_napi even though bq_xmit_all returns that frame again, corrupting memory. Exploitation requires XDP_REDIRECT to the igc interface and enough traffic to fill its transmit queue; the demonstrated consequence is a host crash.
