Removal can set that bit immediately afterwards and free\ndd->port in mtip_hw_exit() while an ioctl still dereferences it. An already\nopen block device can reach the handlers while del_gendisk() is in\nprogress.\n\nSerialize both native and compat ioctls with removal. Set REMOVE_PENDING\nbefore taking the mutex so new callers fail after an in-flight ioctl has\ndrained, and hold the mutex until the port has been torn down.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/4609e0e0be709e974bec9b52c5022136d25e97d3","tags":[]},{"url":"https://git.kernel.org/stable/c/521afbd936ac256b7531470b0b9aa96abf9cd853","tags":[]},{"url":"https://git.kernel.org/stable/c/68940f841d013192086a0f6d7cfbac2cd079e228","tags":[]},{"url":"https://git.kernel.org/stable/c/8283049aa5fcb4e84b2b2928b2888903bb8ee12e","tags":[]},{"url":"https://git.kernel.org/stable/c/8a7799597bd683b6bc251fe2edfa9fd1db568a3a","tags":[]},{"url":"https://git.kernel.org/stable/c/b389dc35a55713ac24a145741e76196fea1663bc","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
