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."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/hisi_sas/hisi_sas_v3_hw.c"],"versions":[{"version":"16fd4a7c5917097e9a3da03b39a92381eee40724","lessThan":"cb414aff28e18e6f5cff9f87ea31376ed8af317b","status":"affected","versionType":"git"},{"version":"16fd4a7c5917097e9a3da03b39a92381eee40724","lessThan":"4867dba229292e13fc19ed865ec1839661952ff9","status":"affected","versionType":"git"},{"version":"16fd4a7c5917097e9a3da03b39a92381eee40724","lessThan":"67b85a88265df19f049241d8c00571a5408f4eeb","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/hisi_sas/hisi_sas_v3_hw.c"],"versions":[{"version":"5.10","status":"affected"},{"version":"0","lessThan":"5.10","status":"unaffected","versionType":"semver"},{"version":"6.18.40","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.1.5","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"6.18.40"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"7.1.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/cb414aff28e18e6f5cff9f87ea31376ed8af317b"},{"url":"https://git.kernel.org/stable/c/4867dba229292e13fc19ed865ec1839661952ff9"},{"url":"https://git.kernel.org/stable/c/67b85a88265df19f049241d8c00571a5408f4eeb"}],"title":"scsi: hisi_sas: Add slave_destroy interface for v3 hw","x_generator":{"engine":"bippy-1.2.0"}}}}
