CVE-2023-52825

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix a race condition of vram buffer unref in svm code prange->svm_bo unref can happen in both mmu callback and a callback after migrate to system ram. Both are async call in different tasks. Sync svm_bo unref operation to avoid random "use-after-free".

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amdkfd: se corrige una condición de ejecución de vram buffer unref en el código svm prange->svm_bo unref puede ocurrir tanto en la devolución de llamada mmu como en una devolución de llamada después de migrar a la memoria RAM del sistema. Ambas son llamadas asíncronas en diferentes tareas. Sincronice la operación svm_bo unref para evitar un "use after free" aleatorio.
