CVE-2025-68321 (GCVE-0-2025-68321)

Title
page_pool: always add GFP_NOWARN for ATOMIC allocations
Summary
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.
Severity

Although globally rate-limited, the resulting persistent disruption can become severe in a reasonable network-appliance deployment."
