Summary
In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Fix payload page pool error cleanup The payload page pool pointer contains an error pointer when its allocation fails. The cleanup path passes that error pointer to page_pool_destroy() instead of destroying the header page pool. This can dereference the error pointer and leave the header page pool allocated. Destroy the header page pool instead.
