Add these missing checks.\n\nIf we allow set_bar() to set e.g. a new BAR size that differs from the\nexisting BAR size, the new address translation range will be smaller than\nthe BAR size already determined by the host, which would mean that a read\npast the new BAR size would pass the iATU untranslated, which could allow\nthe host to read memory not belonging to the new struct pci_epf_bar.\n\nWhile at it, add comments which clarifies the support for dynamically\nchanging the physical address of a BAR. (Which was also missing.)","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/01aaa7935af3050fd1e1e7de50001247c75baeab","https://git.kernel.org/stable/c/3229c15d6267de8e704b4085df8a82a5af2d63eb","https://git.kernel.org/stable/c/3708acbd5f169ebafe1faa519cb28adc56295546","https://git.kernel.org/stable/c/b5cacfd067060c75088363ed3e19779078be2755"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2024-58006","score":0.00291,"percentile":0.21481,"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).
