{"id":"CVE-2026-45868","summary":"pinctrl: single: fix refcount leak in pcs_add_gpio_func()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npinctrl: single: fix refcount leak in pcs_add_gpio_func()\n\nof_parse_phandle_with_args() returns a device_node pointer with refcount\nincremented in gpiospec.np. The loop iterates through all phandles but\nnever releases the reference, causing a refcount leak on each iteration.\n\nAdd of_node_put() calls to release the reference after extracting the\nneeded arguments and on the error path when devm_kzalloc() fails.\n\nThis bug was detected by our static analysis tool and verified by my\ncode review.","modified":"2026-06-27T11:55:47.064321910Z","published":"2026-05-27T12:15:48.311Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45868.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/191bfd5710d6a7f48ba4315d8d3e908dcc15243c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/353353309b0f7afa407df29e455f9d15b5acc296"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3e3b28bb0b6ddc521a4fdd1c1ba0d35017a0796b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/456a60d06c09a92680dc35fabca68024badcc28e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5b9e84d27e310f22c4ba45fedbc4f5baf43dd823"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7814b1431848854b56717086e2b61bea3c59753d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/99cc7352156c65201c675f750e0e77c4c73d93f5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e2e367e56bacb93ce5ac73f0b3297d5c83d38dd4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45868.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45868"},{"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":"a1a277eb76b3507df7c41774048a644aa4dfd096"},{"fixed":"191bfd5710d6a7f48ba4315d8d3e908dcc15243c"},{"fixed":"3e3b28bb0b6ddc521a4fdd1c1ba0d35017a0796b"},{"fixed":"456a60d06c09a92680dc35fabca68024badcc28e"},{"fixed":"99cc7352156c65201c675f750e0e77c4c73d93f5"},{"fixed":"7814b1431848854b56717086e2b61bea3c59753d"},{"fixed":"e2e367e56bacb93ce5ac73f0b3297d5c83d38dd4"},{"fixed":"5b9e84d27e310f22c4ba45fedbc4f5baf43dd823"},{"fixed":"353353309b0f7afa407df29e455f9d15b5acc296"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-45868.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.10.0"},{"fixed":"5.10.252"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.202"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.165"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.128"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.14"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-45868.json"}}],"schema_version":"1.7.5"}
