CVE-2025-39858

In the Linux kernel, the following vulnerability has been resolved: eth: mlx4: Fix IS_ERR() vs NULL check bug in mlx4_en_create_rx_ring Replace NULL check with IS_ERR() check after calling page_pool_create() since this function returns error pointers (ERR_PTR). Using NULL check could lead to invalid pointer dereference.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: eth: mlx4: Solución del error de comprobación IS_ERR() vs NULL en mlx4_en_create_rx_ring Reemplazar la comprobación de NULL con la comprobación IS_ERR() después de llamar a page_pool_create() ya que esta función devuelve punteros de error (ERR_PTR). Usar la comprobación de NULL podría llevar a una desreferencia de puntero inválida.
