{"id":"CVE-2026-98213","summary":"mmc: core: Cancel SDIO IRQ work before freeing host","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmmc: core: Cancel SDIO IRQ work before freeing host\n\nA host controller that uses sdio_signal_irq() schedules host-\u003esdio_irq_work\nfrom its interrupt handler.  That work is only cancelled on the suspend\npath (mmc_sdio_suspend()), not on the remove/free path, so a worker armed\njust before the controller freed its IRQ can run after\nmmc_host_classdev_release() has freed the host and dereference it through\ncontainer_of().\n\nCancel host-\u003esdio_irq_work in mmc_free_host(), like the existing\nhost-\u003edetect drain added by commit 1036f69e2513 (\"mmc: core: Cancel\ndelayed work before releasing host\").\n\nThis issue was found by an in-house static analysis tool.","modified":"2026-10-08T02:52:54.138531984Z","published":"2026-10-06T08:44:49.352Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98213.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0bf3d168a2cc20b120d6b50f0a8ac5b40ff4d589"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1d6e7315ee1c992b4ca42c9b11c5ed0e925a00e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2a863458828ade0671c2bc2e469bbd7f2340eb03"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4553b5004eca9c9eae29a421f1a9c4d5db2c9114"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6feadbecdae60a6324c967f3b1493741083793a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bae1cf4f9902b2065bd78b759c7fe6312855f05e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98213.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98213"},{"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":"682696605c7093d2800c498c04166831e5aedf87"},{"fixed":"bae1cf4f9902b2065bd78b759c7fe6312855f05e"},{"fixed":"0bf3d168a2cc20b120d6b50f0a8ac5b40ff4d589"},{"fixed":"1d6e7315ee1c992b4ca42c9b11c5ed0e925a00e0"},{"fixed":"4553b5004eca9c9eae29a421f1a9c4d5db2c9114"},{"fixed":"2a863458828ade0671c2bc2e469bbd7f2340eb03"},{"fixed":"6feadbecdae60a6324c967f3b1493741083793a3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98213.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.13.0"},{"fixed":"6.1.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.158"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.112"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.54"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.8"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-98213.json"}}],"schema_version":"1.9.0"}
