Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net: lan966x: fix page_pool error handling in lan966x_fdma_rx_alloc_page_pool()<br />
<br />
page_pool_create() can return an ERR_PTR on failure. The return value<br />
is used unconditionally in the loop that follows, passing the error<br />
pointer through xdp_rxq_info_reg_mem_model() into page_pool_use_xdp_mem(),<br />
which dereferences it, causing a kernel oops.<br />
<br />
Add an IS_ERR check after page_pool_create() to return early on failure.
