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->sdio_irq_work in mmc_free_host(), like the existing\nhost->detect 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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0bf3d168a2cc20b120d6b50f0a8ac5b40ff4d589","tags":[]},{"url":"https://git.kernel.org/stable/c/1d6e7315ee1c992b4ca42c9b11c5ed0e925a00e0","tags":[]},{"url":"https://git.kernel.org/stable/c/2a863458828ade0671c2bc2e469bbd7f2340eb03","tags":[]},{"url":"https://git.kernel.org/stable/c/4553b5004eca9c9eae29a421f1a9c4d5db2c9114","tags":[]},{"url":"https://git.kernel.org/stable/c/6feadbecdae60a6324c967f3b1493741083793a3","tags":[]},{"url":"https://git.kernel.org/stable/c/bae1cf4f9902b2065bd78b759c7fe6312855f05e","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
