Description

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

Affected configurations

• linux linux kernel (>= 6.2.1 < 6.6.135) • linux linux kernel (>= 6.7 < 6.12.82) • linux linux kernel (>= 6.13 < 6.18.23) • linux linux kernel (>= 6.19 < 6.19.13) • linux linux kernel 6.2 • linux linux kernel 7.0
