CVE-2025-68321

Estado: AplazadaAlta (7.5)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:N/UI:N sugiere explotación remota sin privilegios (T1190), pero la vulnerabilidad es un defecto en manejo de memoria que causa DoS por agotamiento de recursos en path de recepción de red, no una verdadera explotación remota sino un problema de negación de servicio por fallos de asignación de
