{"id":"CVE-2026-89454","summary":"PCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nPCI: plda: Fix IRQ domain leaks in the error paths of plda_init_interrupts()\n\nplda_init_interrupts() initializes IRQ domains and creates IRQ mapping but\ndoes not unwind them when later step fails.\n\nIf platform_get_irq() or either irq_create_mapping() fails\nin plda_init_interrupts(), the domains are never deinitialized. If\nirq_create_mapping() fails, port-\u003eintx_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-\u003eintx_irq separately first.\n\nThis issue was found by automated review of sashiko-bot\n\n[mani: commit log]","modified":"2026-09-13T03:47:18.202714693Z","published":"2026-09-11T19:43:18.717Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89454.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/01b05cebe1e862e31e382359848d7dca02525a4f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/19a30bbb6477bfd7e3109b7a2943e6597ee9de37"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4b575052ea65423693726a21826d783cf3f1745e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e54e8d2a0f9c8bf251ae4385ea4f4a68840fedad"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/89xxx/CVE-2026-89454.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89454"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4602c370bdf6946b4e954a3db0ef5958aac2b7b4"},{"fixed":"01b05cebe1e862e31e382359848d7dca02525a4f"},{"fixed":"4b575052ea65423693726a21826d783cf3f1745e"},{"fixed":"e54e8d2a0f9c8bf251ae4385ea4f4a68840fedad"},{"fixed":"19a30bbb6477bfd7e3109b7a2943e6597ee9de37"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89454.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.11.0"},{"fixed":"6.12.109"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.50"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-89454.json"}}],"schema_version":"1.9.0"}
