CVE-2026-23453
Description
In the Linux kernel, the following vulnerability has been resolved: net: ti: icssg-prueth: Fix memory leak in XDP_DROP for non-zero-copy mode Page recycling was removed from the XDP_DROP path in emac_run_xdp() to avoid conflicts with AF_XDP zero-copy mode, which uses xsk_buff_free() instead. However, this causes a memory leak when running XDP programs that drop packets in non-zero-copy mode (standard page pool mode). The pages are never returned to the page pool, leading to OOM conditions. Fix this by handling cleanup in the caller, emac_rx_packet(). When emac_run_xdp() returns ICSSG_XDP_CONSUMED for XDP_DROP, the caller now recycles the page back to the page pool. The zero-copy path, emac_rx_packet_zc() already handles cleanup correctly with xsk_buff_free().
