{"id":"CVE-2026-72182","summary":"power: supply: charger-manager: fix refcount leak in is_full_charged()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\npower: supply: charger-manager: fix refcount leak in is_full_charged()\n\nIn is_full_charged(), power_supply_get_by_name() is called to\nobtain a reference to the fuel_gauge power supply. If the\nvoltage check (uV \u003e= desc-\u003efullbatt_uV) succeeds, the function\nreturns true directly without releasing the reference, leaking\nthe refcount.\n\nFix this by setting a flag and jumping to the out label where\npower_supply_put() properly drops the reference.","modified":"2026-08-16T03:48:37.448839078Z","published":"2026-08-15T05:53:45.189Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72182.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/193e6471e985c2f25d09b3fe96ec52f4eab89bd4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3999f47e4bbf864e3c7fbfd813fb2f651e6b5714"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4373cfa38ead58f980362c841b0d0bdf8c4d956c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6f75912cc6ff4c05ff13af351c4eea49b6b3c078"},{"type":"WEB","url":"https://git.kernel.org/stable/c/93b99b63ad5657225faf702670ddfeddf1f0ae29"},{"type":"WEB","url":"https://git.kernel.org/stable/c/afe3202c30bdff0635818ab525fe2694309d2692"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e44ad91e9f75f3e3ccbdb85ffe699471f9675e5b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e8631b883338ea4c3b5d8ddfbe16407af9f0b4b9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72182.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72182"},{"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":"e132fc6bb89bd307cfcdb8ba24afcd1985261485"},{"fixed":"afe3202c30bdff0635818ab525fe2694309d2692"},{"fixed":"93b99b63ad5657225faf702670ddfeddf1f0ae29"},{"fixed":"6f75912cc6ff4c05ff13af351c4eea49b6b3c078"},{"fixed":"e44ad91e9f75f3e3ccbdb85ffe699471f9675e5b"},{"fixed":"3999f47e4bbf864e3c7fbfd813fb2f651e6b5714"},{"fixed":"193e6471e985c2f25d09b3fe96ec52f4eab89bd4"},{"fixed":"e8631b883338ea4c3b5d8ddfbe16407af9f0b4b9"},{"fixed":"4373cfa38ead58f980362c841b0d0bdf8c4d956c"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72182.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.10.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72182.json"}}],"schema_version":"1.9.0"}
