How to fix?

Upgrade SLES:16.0.0 kernel-source to version 6.12.0-160000.36.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-source package and not the kernel-source package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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.
