CVE-2024-42091

  2. Vulnerabilities (CVE)
  3. CVE-2024-42091
In the Linux kernel, the following vulnerability has been resolved: drm/xe: Check pat.ops before dumping PAT settings We may leave pat.ops unset when running on brand new platform or when running as a VF. While the former is unlikely, the latter is valid (future) use case and will cause NPD when someone will try to dump PAT settings by debugfs. It's better to check pointer to pat.ops instead of specific .dump hook, as we have this hook always defined for every .ops variant.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/xe: verifique pat.ops antes de volcar la configuración de PAT. Podemos dejar pat.ops sin configurar cuando se ejecuta en una plataforma nueva o cuando se ejecuta como VF. Si bien lo primero es poco probable, el segundo es un caso de uso válido (futuro) y causará NPD cuando alguien intente volcar la configuración de PAT mediante debugfs. Es mejor marcar el puntero a pat.ops en lugar del gancho .dump específico, ya que siempre tenemos este gancho definido para cada variante de .ops.
