Description
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.

Can you explain this vulnerability to me?

This vulnerability relates to the Linux kernel's page pool mechanism where driver authors often forget to add the GFP_NOWARN flag for page allocations made with ATOMIC context. Without GFP_NOWARN, allocation failures during out-of-memory (OOM) conditions can cause unnecessary warnings or issues. The fix ensures that page pool allocations add GFP_NOWARN by default for ATOMIC allocations to avoid these problems.


How can this vulnerability impact me? :

The vulnerability can cause annoying warnings or failures during network receive (Rx) operations when the system is under out-of-memory (OOM) conditions, potentially affecting network performance or stability. By not adding GFP_NOWARN, the system may generate unnecessary warnings that could disrupt normal operation or debugging.
