Those\nentries do not own a reference, because the iterator drops the previous\ndevice reference on each step. The cached pointer is then dereferenced\nlater when handling OCTEON_VF_FLR_REQUEST.\n\nReplace the cached VF mapping with runtime lookup on the mailbox DPI\nring: derive the VF index from q_no, resolve the VF via exported PCI\nIOV helpers, validate it with the PF pointer and VF ID, then issue\npcie_flr() and drop the reference with pci_dev_put(). Remove the\nunused VF lookup table initialization and cleanup.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","score":9.3},"cwes":[],"references":["https://git.kernel.org/stable/c/08ff33dce6f91510bb296a753a232db0ca3fd3d8","https://git.kernel.org/stable/c/1cf5c6a80adc31456f3e93b2922a2446fd63e2c4","https://git.kernel.org/stable/c/5c0e3ba4f500fd4314ceb42f07f16bc445156431","https://git.kernel.org/stable/c/81acef3a247fd523513a2e9f71de1c167bc0f882","https://git.kernel.org/stable/c/e3b20de8d7c06c8f1a0ded1e52be9d282609c3da"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-72329","score":0.00193,"percentile":0.08896,"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).
