Title
drm/amdgpu: change vm->task_info handling
Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: change vm->task_info handling This patch changes the handling and lifecycle of vm->task_info object. The major changes are: - vm->task_info is a dynamically allocated ptr now, and its uasge is reference counted. - introducing two new helper funcs for task_info lifecycle management - amdgpu_vm_get_task_info: reference counts up task_info before returning this info - amdgpu_vm_put_task_info: reference counts down task_info - last put to task_info() frees task_info from the vm. This patch also does logistical changes required for existing usage of vm->task_info. V2: Do not block all the prints when task_info not found (Felix) V3: Fixed review comments from Felix - Fix wrong indentation - No debug message for -ENOMEM - Add NULL check for task_info - Do not duplicate the debug messages (ti vs no ti) - Get first reference of task_info in vm_init(), put last in vm_fini() V4: Fixed review comments from Felix - fix double reference increment in create_task_info - change amdgpu_vm_get_task_info_pasid - additional changes in amdgpu_gem.c while porting

No capability check exists on the amdgpu CS ioctl path.\nUI:N - The attacking process performs every step itself \u2014 job submission, fd close, and heap grooming \u2014 with no action required from any other user.\nS:U - The stale-pointer read and its consequences stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The use-after-free reads a freed kernel heap object and emits its contents into the devcoredump blob and kernel log, and the unterminated %s print can read past the field, disclosing arbitrary reallocated kernel heap data that the attacker can groom.\nI:H - Use-after-free of a slab object whose contents an attacker can control by reallocation constitutes memory corruption exploitable beyond a simple read; the unsynchronized task_info lifetime is a general object-lifetime confusion, so integrity impact is scored High per UAF guidance.\nA:H - Dereferencing the dangling vm pointer during GPU reset can oops or panic the kernel if the slab page has been returned to the page allocator, and it occurs in the non-recoverable GPU recovery path, which the attacker can trigger repeatedly."

Los cambios principales son: - vm-\u0026gt;task_info ahora es un ptr asignado din\u00e1micamente y su uso se cuenta por referencia. - presentamos dos nuevas funciones auxiliares para la gesti\u00f3n del ciclo de vida de task_info - amdgpu_vm_get_task_info: la referencia cuenta task_info antes de devolver esta informaci\u00f3n - amdgpu_vm_put_task_info: la referencia cuenta atr\u00e1s task_info - la \u00faltima entrada en task_info() libera task_info de la m\u00e1quina virtual. Este parche tambi\u00e9n realiza cambios log\u00edsticos necesarios para el uso existente de vm-\u0026gt;task_info. V2: No bloquear todas las impresiones cuando no se encuentra task_info (Felix) V3: Se corrigieron los comentarios de revisi\u00f3n de Felix - Se corrigi\u00f3 la sangr\u00eda incorrecta - No hay mensaje de depuraci\u00f3n para -ENOMEM - Agregar verificaci\u00f3n NULL para task_info - No se duplican los mensajes de depuraci\u00f3n (ti vs no ti) - Obtenga la primera referencia de task_info en vm_init(), col\u00f3quela \u00faltima en vm_fini() V4: Se corrigieron los comentarios de revisi\u00f3n de Felix - se corrigi\u00f3 el incremento de doble referencia en create_task_info - se cambi\u00f3 amdgpu_vm_get_task_info_pasid - cambios adicionales en amdgpu_gem.c durante la portabilidad"
