CVE-2026-31646
Estado: AnalizadaMedia (5.5)—
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.
CVSS
- Versión: 3.1
