Descriptions

In the Linux kernel, the following vulnerability has been resolved:

drm/panfrost: Fix the error path in panfrost_mmu_map_fault_addr()

Subject: [PATCH] drm/panfrost: Fix the error path in
panfrost_mmu_map_fault_addr()

If some the pages or sgt allocation failed, we shouldn't release the
pages ref we got earlier, otherwise we will end up with unbalanced
get/put_pages() calls. We should instead leave everything in place
and let the BO release function deal with extra cleanup when the object
is destroyed, or let the fault handler try again next time it's called.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/panfrost: corrige la ruta de error en panfrost_mmu_map_fault_addr() Asunto: [PATCH] drm/panfrost: corrige la ruta de error en panfrost_mmu_map_fault_addr() Si algunas páginas o la asignación de sgt fallaron, No deberíamos publicar la referencia de páginas que obtuvimos anteriormente, de lo contrario terminaremos con llamadas get/put_pages() desequilibradas. En su lugar, deberíamos dejar todo en su lugar y dejar que la función de liberación de BO se encargue de una limpieza adicional cuando se destruya el objeto, o dejar que el controlador de fallos lo intente nuevamente la próxima vez que se llame.
