      <title>CVE-2026-23453 — net: ti: icssg-prueth: Fix memory leak in XDP_DROP for non-zero-copy mode</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-23453</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;net: ti: icssg-prueth: Fix memory leak in XDP_DROP for non-zero-copy mode&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;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.&lt;/p&gt;
&lt;p&gt;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().&lt;/p&gt;</description>
