{"id":"CVE-2024-35986","summary":"phy: ti: tusb1210: Resolve charger-det crash if charger psy is unregistered","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nphy: ti: tusb1210: Resolve charger-det crash if charger psy is unregistered\n\nThe power_supply frame-work is not really designed for there to be\nlong living in kernel references to power_supply devices.\n\nSpecifically unregistering a power_supply while some other code has\na reference to it triggers a WARN in power_supply_unregister():\n\n\tWARN_ON(atomic_dec_return(&psy-\u003euse_cnt));\n\nFolllowed by the power_supply still getting removed and the\nbacking data freed anyway, leaving the tusb1210 charger-detect code\nwith a dangling reference, resulting in a crash the next time\ntusb1210_get_online() is called.\n\nFix this by only holding the reference in tusb1210_get_online()\nfreeing it at the end of the function. Note this still leaves\na theoretical race window, but it avoids the issue when manually\nrmmod-ing the charger chip driver during development.","modified":"2026-04-16T04:38:54.995134919Z","published":"2024-05-20T09:47:53.074Z","related":["SUSE-SU-2024:2135-1","SUSE-SU-2024:2203-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1","SUSE-SU-2025:20028-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20249-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/35xxx/CVE-2024-35986.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/25b3498485ac281e5851700e33b97f12c9533fd8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/73224a5d2180066c7fe05b4656647601ba08d588"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9827caa5105fb16d1fae2e75c8d0e4662014b3ca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf6e4ee5c43690e4c5a8a057bbcd4ff986bed052"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/35xxx/CVE-2024-35986.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-35986"},{"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":"48969a5623ed918713552e2b4f9d391c89b5e838"},{"fixed":"25b3498485ac281e5851700e33b97f12c9533fd8"},{"fixed":"73224a5d2180066c7fe05b4656647601ba08d588"},{"fixed":"9827caa5105fb16d1fae2e75c8d0e4662014b3ca"},{"fixed":"bf6e4ee5c43690e4c5a8a057bbcd4ff986bed052"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-35986.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
