Linux Kernel mlx4 Ethernet Driver NULL Pointer Dereference Vulnerability

Vulnerability

A vulnerability in the Linux kernel's mlx4 Ethernet driver can lead to a NULL pointer dereference. This issue arises in the 'mlx4_en_create_rx_ring' function, where a NULL check was improperly used after calling 'page_pool_create()'. The 'page_pool_create()' function can return error pointers, and the NULL check could result in an invalid pointer dereference. This vulnerability affects the Linux kernel stable tree.

Impact

Exploitation of this vulnerability causes a NULL pointer dereference, leading to a crash of the affected kernel module.
