CVE-2025-68321: page_pool: always add GFP_NOWARN for ATOMIC allocations

Published Dec 16, 2025
·
Updated

In the Linux kernel, the following vulnerability has been resolved:

pagepool: always add GFPNOWARN for ATOMIC allocations

Driver authors often forget to add GFPNOWARN 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 GFPNOWARN for ATOMIC allocations by default.
