Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel up to 5.15.196/6.1.158/6.6.116/6.12.57/6.17.7. Affected is the function page_pool. The manipulation with an unknown input leads to a allocation of resources vulnerability. CWE is classifying the issue as CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. The impact remains unknown. CVE summarizes:

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.

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2025-68321 since 12/16/2025. There are known technical details, but no exploit is available.
