In the Linux kernel, the following vulnerability has been resolved:
page_pool: always add GFP_NOWARN for ATOMIC allocations
Driver authors often forget to add GFP_NOWARN for page allocation
from the datapath. This is annoying to users as OOMs are a fact
of life, and we pretty much expect network Rx to hit page allocation
failures during OOM. Make page pool add GFP_NOWARN for ATOMIC allocations
by default.
