Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
net: lan966x: fix page pool leak in error paths
lan966x_fdma_rx_alloc() creates a page pool but does not destroy it if
the subsequent fdma_alloc_coherent() call fails, leaking the pool.
Similarly, lan966x_fdma_init() frees the coherent DMA memory when
lan966x_fdma_tx_alloc() fails but does not destroy the page pool that
was successfully created by lan966x_fdma_rx_alloc(), leaking it.
Add the missing page_pool_destroy() calls in both error paths.
