{"id":"CVE-2025-37946","summary":"s390/pci: Fix duplicate pci_dev_put() in disable_slot() when PF has child VFs","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ns390/pci: Fix duplicate pci_dev_put() in disable_slot() when PF has child VFs\n\nWith commit bcb5d6c76903 (\"s390/pci: introduce lock to synchronize state\nof zpci_dev's\") the code to ignore power off of a PF that has child VFs\nwas changed from a direct return to a goto to the unlock and\npci_dev_put() section. The change however left the existing pci_dev_put()\nuntouched resulting in a doubple put. This can subsequently cause a use\nafter free if the struct pci_dev is released in an unexpected state.\nFix this by removing the extra pci_dev_put().","modified":"2026-04-02T12:47:38.773889Z","published":"2025-05-20T16:01:43.162Z","related":["SUSE-SU-2025:02249-1","SUSE-SU-2025:02254-1","SUSE-SU-2025:02307-1","SUSE-SU-2025:02333-1","SUSE-SU-2025:02335-1","SUSE-SU-2025:02538-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:20475-1","SUSE-SU-2025:20483-1","SUSE-SU-2025:20493-1","SUSE-SU-2025:20498-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37946.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/05a2538f2b48500cf4e8a0a0ce76623cc5bafcf1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/957529baef142d95e0d1b1bea786675bd47dbe53"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c488f8b53e156d6dcc0514ef0afa3a33376b8f9e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/37xxx/CVE-2025-37946.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-37946"},{"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":"bcb5d6c769039c8358a2359e7c3ea5d97ce93108"},{"fixed":"c488f8b53e156d6dcc0514ef0afa3a33376b8f9e"},{"fixed":"957529baef142d95e0d1b1bea786675bd47dbe53"},{"fixed":"05a2538f2b48500cf4e8a0a0ce76623cc5bafcf1"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-37946.json"}}],"schema_version":"1.7.5"}
