{"id":"CVE-2026-98527","summary":"gpio: zynq: fix runtime PM leak on request error path","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: zynq: fix runtime PM leak on request error path\n\npm_runtime_get_sync() leaves the usage counter incremented even when it\nfails, and zynq_gpio_request() returns the error without dropping it.\n\ngpiolib does not call -\u003efree() when -\u003erequest() fails, so zynq_gpio_free(),\nwhich holds the only matching pm_runtime_put(), never runs. The reference\nis leaked and the controller can no longer runtime-suspend, so its clock\nstays enabled.\n\nSwitch to pm_runtime_resume_and_get(), which only increments the usage\ncounter on success.","modified":"2026-10-19T02:46:31.221995109Z","published":"2026-10-18T15:17:45.684Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98527.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/25c08be2a5e7715f19a6e02bbe9b0e5f01c77aac"},{"type":"WEB","url":"https://git.kernel.org/stable/c/58a417a19d80141fff3abe6004e2e47285506e73"},{"type":"WEB","url":"https://git.kernel.org/stable/c/60a76cdd92e25f576dc58d756a565760dde1f7a1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6e05f1c614a57a5d4c364dd12e20c6fd012f9d3e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6e20dabffbcd7b222d8e7bb85a7d8e8325df7699"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3e9b7f7c9558f8c9592f8f817557bff98707bb3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e380fba02908b809f5bbef371259003cf5887bb4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e9438ab5328a177c9c0e5df87eb92a7162841e98"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98527.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98527"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3242ba117e9bd29eb748afd6f6fbfbd6dd7cfe52"},{"fixed":"e380fba02908b809f5bbef371259003cf5887bb4"},{"fixed":"a3e9b7f7c9558f8c9592f8f817557bff98707bb3"},{"fixed":"60a76cdd92e25f576dc58d756a565760dde1f7a1"},{"fixed":"25c08be2a5e7715f19a6e02bbe9b0e5f01c77aac"},{"fixed":"6e05f1c614a57a5d4c364dd12e20c6fd012f9d3e"},{"fixed":"58a417a19d80141fff3abe6004e2e47285506e73"},{"fixed":"6e20dabffbcd7b222d8e7bb85a7d8e8325df7699"},{"fixed":"e9438ab5328a177c9c0e5df87eb92a7162841e98"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98527.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.17.0"},{"fixed":"5.10.271"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.222"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98527.json"}}],"schema_version":"1.9.0"}
