{"id":"CVE-2026-90280","summary":"phy: qcom: qmp-usb: Fix possible NULL-deref on early runtime suspend","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nphy: qcom: qmp-usb: Fix possible NULL-deref on early runtime suspend\n\nThere is a small window where the runtime suspend callback may run\nafter pm_runtime_enable() and before pm_runtime_forbid(). In this\ncase, a crash occurs because runtime suspend/resume dereferences\nqmp-\u003ephy pointer, which is not yet initialized:\n        `if (!qmp-\u003ephy-\u003einit_count) {`\n\nThis can also happen if user re-enables runtime-pm via the sysfs\nattribute before qmp phy is initialized.\n\nSimilarly to other qcom phy drivers, introduce a qmp-\u003ephy_initialized\nvariable that can be used to avoid relying on the possibly uninitialized\nphy pointer.","modified":"2026-09-18T03:48:36.934262891Z","published":"2026-09-17T16:08:11.281Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90280.json","cna_assigner":"Linux"},"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/03455404fb6cbfd65842695df26739853fc1516b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/142c5593379273264474f31d5956b1a0065cd576"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5547fd950d6bf72de861b6934341e7bb0888640c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9b28287c5dea7650e6dd317591b9e82b6e145365"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f4e39ab1b2009a89c60e4cb9dbefb8140d405eff"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/90xxx/CVE-2026-90280.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90280"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e464a3180a43b6596bd267f9f274e1793bfb8150"},{"fixed":"9b28287c5dea7650e6dd317591b9e82b6e145365"},{"fixed":"f4e39ab1b2009a89c60e4cb9dbefb8140d405eff"},{"fixed":"5547fd950d6bf72de861b6934341e7bb0888640c"},{"fixed":"03455404fb6cbfd65842695df26739853fc1516b"},{"fixed":"142c5593379273264474f31d5956b1a0065cd576"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90280.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.6.0"},{"fixed":"6.6.157"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.52"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-90280.json"}}],"schema_version":"1.9.0"}
