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. Oops: general protection fault, probably for non-canonical     address 0xdffffc0000000008: 0000 [#1] SMP KASAN PTI RIP: 0010:cxl_calc_interleave_pos+0x26/0x810     [cxl_core] Call Trace: <TASK> cxl_region_attach+0xc50/0x2140 [cxl_core] cxl_add_to_region+0x321/0x2330     [cxl_core] discover_region+0x92/0x150 [cxl_port] device_for_each_child+0xf3/0x170     cxl_port_probe+0x150/0x200 [cxl_port] cxl_bus_probe+0x4f/0xa0 [cxl_core] really_probe+0x1c8/0x960

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. (CVE-2026-74274)

Note that Nessus relies on the presence of the package as reported by the vendor.
