Linux/Unix 主機上安裝了一個或多個受到弱點影響的套件，且供應商未提供可用的修補程式。

  - 已解決 Linux 核心中的下列弱點：cxl/region: Fill first free targets[] slot during auto-discovery Any invalid endpoint decoder pointer in the target array of an active region is not allowed by cxl driver. This means cxl driver always assumes the first p->nr_targets entries of the target array in an auto-assembly region are valid. However, there are scenarios that could leave NULL endpoint decoder pointer holes in the target array. 1. When cxl_cancel_auto_attach() removes an endpoint decoder from a target array, the target slot is set to NULL. If the removed endpoint decoder is not the last element in the target array, the target array will contain a NULL hole. 2. When a auto-assembly region removes an assigned endpoint decoder, if the removed endpoint decoder is not the last element in the target array, always remains a NULL hole in the target array. When a NULL pointer hole exists in a region's target array, it introduces two potential problems: 1. Access an endpoint decoder via a NULL pointer. it always trigger calltrace like that.

Not having enough valid endpoint decoders attached to an auto-assembly region. if an auto-assembly region is created with lock flag or assigned endpoint decoder with lock flag, which means assigned endpoint decoder will not be reset during detaching, they could re-attach to the auto-assembly region again. But cxl region driver relies on p->nr_targets to verify whether the required number of endpoint decoders has been attached, and NULL endpoint decoder pointers are still counted in that case. To fix above issues, adjust cxl_region_attach_auto() logic to find the first free target slot for endpoint decoder attachment, this ensures NULL holes in the target array are filled, rather than adding new endpoint decoders at the tail of the target array.

Nessus は、ベンダーによって報告されたパッケージの存在に依存していることに注意してください。

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: cxl/region: Fill first free targets[]     slot during auto-discovery Any invalid endpoint decoder pointer in the target array of an active region is     not allowed by cxl driver. This means cxl driver always assumes the first p->nr_targets entries of the     target array in an auto-assembly region are valid. However, there are scenarios that could leave NULL     endpoint decoder pointer holes in the target array. 1. When cxl_cancel_auto_attach() removes an endpoint     decoder from a target array, the target slot is set to NULL. If the removed endpoint decoder is not the     last element in the target array, the target array will contain a NULL hole. 2. When a auto-assembly     region removes an assigned endpoint decoder, if the removed endpoint decoder is not the last element in     the target array, always remains a NULL hole in the target array. When a NULL pointer hole exists in a     region's target array, it introduces two potential problems: 1. Access an endpoint decoder via a NULL     pointer. it always trigger calltrace like that.
