CVE-2025-68321
Full vulnerability record from the local CVENow database.
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.

"value": "En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta:\n\npage_pool: siempre añadir GFP_NOWARN para asignaciones ATOMIC\n\nLos autores de controladores a menudo olvidan añadir GFP_NOWARN para la asignación de páginas desde la ruta de datos. Esto es molesto para los usuarios ya que los OOM son un hecho de la vida, y prácticamente esperamos que el Rx de red encuentre fallos en la asignación de páginas durante OOM. Hacer que el page pool añada GFP_NOWARN para asignaciones ATOMIC por defecto."
