n the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: Cleanup partial engine discovery failures If we abort driver initialisation in the middle of gt/engine discovery, some engines will be fully setup and some not. Those incompletely setup engines only have 'engine->release == NULL' and so will leak any of the common objects allocated. v2: - Drop the destroy_pinned_context() helper for now. It's not really worth it with just a single callsite at the moment. (Janusz)

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/i915/gt: Limpieza de fallas parciales en el descubrimiento del motor Si abortamos la inicialización del controlador en medio del descubrimiento de gt/engine, algunos motores estarán completamente configurados y otros no. Esos motores configurados de forma incompleta solo tienen 'motor->liberación == NULL' y, por lo tanto, filtrarán cualquiera de los objetos comunes asignados. v2: - Suelta el ayudante destroy_pinned_context() por ahora. Realmente no vale la pena con un solo sitio de llamada en este momento. (Janusz)
