If\nirq_create_mapping() fails, port->intx_irq stays initialized.\n\nHence, remove the IRQ domains in the error path by calling\nplda_pcie_irq_domain_deinit().\n\nSince plda_pcie_irq_domain_deinit() now disposes of the intx_irq and\nmsi_irq mappings itself before removing their domains, the msi_irq\nmapping failure path can go directly to err_irq_domain_deinit instead of\ndisposing of port->intx_irq separately first.\n\nThis issue was found by automated review of sashiko-bot\n\n[mani: commit log]"}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/pci/controller/plda/pcie-plda-host.c"],"versions":[{"version":"4602c370bdf6946b4e954a3db0ef5958aac2b7b4","lessThan":"01b05cebe1e862e31e382359848d7dca02525a4f","status":"affected","versionType":"git"},{"version":"4602c370bdf6946b4e954a3db0ef5958aac2b7b4","lessThan":"4b575052ea65423693726a21826d783cf3f1745e","status":"affected","versionType":"git"},{"version":"4602c370bdf6946b4e954a3db0ef5958aac2b7b4","lessThan":"e54e8d2a0f9c8bf251ae4385ea4f4a68840fedad","status":"affected","versionType":"git"},{"version":"4602c370bdf6946b4e954a3db0ef5958aac2b7b4","lessThan":"19a30bbb6477bfd7e3109b7a2943e6597ee9de37","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/plda/pcie-plda-host.c"],"versions":[{"version":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","status":"unaffected","versionType":"semver"},{"version":"6.12.109","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.50","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.4","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","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":"6.11","versionEndExcluding":"6.12.109"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.18.50"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"7.2.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/01b05cebe1e862e31e382359848d7dca02525a4f"},{"url":"https://git.kernel.org/stable/c/4b575052ea65423693726a21826d783cf3f1745e"},{"url":"https://git.kernel.org/stable/c/e54e8d2a0f9c8bf251ae4385ea4f4a68840fedad"},{"url":"https://git.kernel.org/stable/c/19a30bbb6477bfd7e3109b7a2943e6597ee9de37"}],"title":"PCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts()","x_generator":{"engine":"bippy-1.2.0"}}}}
