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.)"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/pci/controller/dwc/pcie-designware-ep.c"],"versions":[{"version":"4284c88fff0efc4e418abb53d78e02dc4f099d6c","lessThan":"b5cacfd067060c75088363ed3e19779078be2755","status":"affected","versionType":"git"},{"version":"4284c88fff0efc4e418abb53d78e02dc4f099d6c","lessThan":"3229c15d6267de8e704b4085df8a82a5af2d63eb","status":"affected","versionType":"git"},{"version":"4284c88fff0efc4e418abb53d78e02dc4f099d6c","lessThan":"3708acbd5f169ebafe1faa519cb28adc56295546","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/pci/controller/dwc/pcie-designware-ep.c"],"versions":[{"version":"6.0","status":"affected"},{"version":"0","lessThan":"6.0","status":"unaffected","versionType":"semver"},{"version":"6.12.14","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.13.3","lessThanOrEqual":"6.13.*","status":"unaffected","versionType":"semver"},{"version":"6.14","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":"6.0","versionEndExcluding":"6.12.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.13.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.14"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b5cacfd067060c75088363ed3e19779078be2755"},{"url":"https://git.kernel.org/stable/c/3229c15d6267de8e704b4085df8a82a5af2d63eb"},{"url":"https://git.kernel.org/stable/c/3708acbd5f169ebafe1faa519cb28adc56295546"}],"title":"PCI: dwc: ep: Prevent changing BAR size/flags in pci_epc_set_bar()","x_generator":{"engine":"bippy-1.2.0"}}}}
