Calling NGBE_INTR_MISC(wx) dereferences\nwx->msix_entry->entry, leading to a NULL pointer dereference crash.\n\nThis issue was introduced by fixing the IRQ vector when the number of\nVFs is 7. Fix the issue by explicitly checking `pdev->msix_enabled` to\ndetermine the correct vector index.\n\nAdditionally, as a side fix, set the interrupt mask to BIT(0) for the\nnon-MSI-X fallback. In MSI/INTx mode, the MISC and queue interrupts\nshare vector 0, and the WX_PX_MISC_IVAR register is only valid in the\nMSI-X case. Thus, BIT(0) is the correct mask for the miscellaneous cause\nwhen MSI-X is disabled.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":[],"references":["https://git.kernel.org/stable/c/0ab482b2195edc000262f0eae1cdcb416b8f335d","https://git.kernel.org/stable/c/5f3a13e0bb5ebcc1ca2dfda42ea40b9f3c2be6ea","https://git.kernel.org/stable/c/cef4c5b9aca24651d069adf9462b221df6a2a669"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:17.453294893+00:00"},"epss":{"cve":"CVE-2026-74741","score":0.00609,"percentile":0.49187,"date":"2026-10-31"},"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).
