This function is called by\npci_for_each_dma_alias() which based on topology decides to send\noriginal or alias device details in first argument.\n\nThis meant that the source devid used to look up and copy the DTE\nmay be incorrect, leading to wrong or stale DTE entries being\npropagated to alias device.\n\nFix this by passing the original pdev as the opaque data argument to\nboth the direct clone_alias() call and pci_for_each_dma_alias(). Inside\nclone_alias(), retrieve the original device from data and compute devid\nfrom it.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":8.8},"cwes":["CWE-681"],"references":["https://git.kernel.org/stable/c/166a08644aa509e5d27e154d7fa774f4181df9e0","https://git.kernel.org/stable/c/20b3c566e2702e5d4d0545be8a97029a2eebcc0e","https://git.kernel.org/stable/c/dae251ff11d2d2208a029f98923756831cefec46","https://git.kernel.org/stable/c/dbd76a537d8cb814e7f5b795ab21ecb7949c821d","https://git.kernel.org/stable/c/faad224fe0f0857a04ff2eb3c90f0de57f47d0f3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-53053","score":0.00129,"percentile":0.02521,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
