CVE-2026-23453

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