{"id":"CVE-2026-90028","summary":"usb: typec: hd3ss3220: track VBUS enable state per consumer","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nusb: typec: hd3ss3220: track VBUS enable state per consumer\n\nregulator_is_enabled() reports the aggregate regulator state, not\nwhether this consumer holds an enable reference. If another consumer\nenables VBUS first, the driver can skip its own regulator_enable() call\nand later attempt to drop a reference it never acquired, triggering an\nunbalanced regulator disable warning.\n\nTrack successful enable and disable calls locally. Keep the state\nunchanged when an operation fails so a later role or ID notification\nretries the operation while this consumer keeps balanced references.","modified":"2026-09-18T03:48:34.960377775Z","published":"2026-09-16T10:33:30.400Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90028.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/c9a48db776d7184981630ecc01a3ad30a8f7dc24"},{"type":"WEB","url":"https://git.kernel.org/stable/c/df7cd3908e07503fa7e9737dacf44208530e58d9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90028.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90028"},{"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":"b3f9d6e491fda73c319547881b78cdd2a222b293"},{"fixed":"df7cd3908e07503fa7e9737dacf44208530e58d9"},{"fixed":"c9a48db776d7184981630ecc01a3ad30a8f7dc24"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90028.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.2.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90028.json"}}],"schema_version":"1.9.0"}
