{"id":"CVE-2026-98565","summary":"net: dsa: mt7530: fix NULL dereference on unbind of MT7531 and MT7621","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: dsa: mt7530: fix NULL dereference on unbind of MT7531 and MT7621\n\nThe core and io supplies are only requested for ID_MT7530: both the\ndevm_regulator_get() in probe and the regulator_enable() in\nmt7530_setup() are guarded by the switch id, but mt7530_remove()\ndisables them unconditionally. On an MT7621 or an MT7531 both pointers\nare still NULL from devm_kzalloc(), so rmmod or a sysfs unbind calls\nregulator_disable() on NULL.","modified":"2026-10-19T02:45:28.302983395Z","published":"2026-10-18T15:18:31.836Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98565.json"},"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/62c0e38b2e5034184d4502ce77bd178b29e59b83"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aae2a1f1e3a0ac5eeb439262a2328a2a392413ac"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bd172580e624bac00d83abd5c4320d2e14d853bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c2cdef41e0b4d8ed23a5b41e6ad4e64594e055e4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e9a5298532780ecdd05c3220f3e1e3067b3537c3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98565.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98565"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ddda1ac116c852bb969541ed53cffef7255c4961"},{"fixed":"bd172580e624bac00d83abd5c4320d2e14d853bc"},{"fixed":"e9a5298532780ecdd05c3220f3e1e3067b3537c3"},{"fixed":"62c0e38b2e5034184d4502ce77bd178b29e59b83"},{"fixed":"aae2a1f1e3a0ac5eeb439262a2328a2a392413ac"},{"fixed":"c2cdef41e0b4d8ed23a5b41e6ad4e64594e055e4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98565.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.1.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.55"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.9"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98565.json"}}],"schema_version":"1.9.0"}
