Note: Versions mentioned in the description apply only to the upstream kernel-uek-modules-wireless package and not the kernel-uek-modules-wireless package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

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.
