"value": "AV:L - The bug is reached when libsas tears down SCSI devices after a remote SAS PHY link reset (sas_revalidate_domain -> sas_destruct_devices) or when root unloads the hisi_sas v3 module; both require local kernel/driver activity, not remote network packets.\nAC:L - An attacker who controls a rogue SAS endpoint can repeatedly force link resets and race them against driver teardown; the failure is a deterministic missing sdev_destroy/device_link_remove on the hot path rather than a rare layout-dependent condition.\nPR:N - Triggering remote PHY link resets and SAS domain revalidation requires no Linux credentials—only a malicious or misbehaving device on the SAS fabric; root is only needed for the concurrent module-unload half of the reported race, not the dangling-link defect itself.\nUI:N - Exploitation does not require a victim to open files or mount filesystems; a rogue SAS device or automated PHY error/link-reset handling can drive the vulnerable teardown while the HBA is active.\nS:U - Impact is confined to the host kernel's SCSI/SAS driver and PM-runtime device-link state on the affected HiSilicon v3 HBA; it does not cross VM, container, or IOMMU security boundaries.\nC:H - Without sdev_destroy, managed device_links from scsi_device to hisi_hba survive consumer teardown, leaving consumer pointers to freed scsi_device memory that later hba PM-runtime or device-link walks can dereference (use-after-free read primitive).\nI:H - Stale managed device_links referencing freed scsi_devices corrupt kernel heap/link metadata and can be leveraged for further memory corruption during subsequent hba link management, matching kernel CNA guidance for lifecycle/UAF bugs.\nA:H - The reported race triggers WARN_ON in __device_links_no_driver (kernel oops under panic_on_warn) and dangling PM-runtime device_links from unfreed teardown can crash the host on later hba suspend/resume or module removal."
