The array is shared by the adapter's connections\nand initialized with XA_FLAGS_LOCK_BH.  However, chcr_ktls_dev_del() and\nthe chcr_ktls_dev_add() error path use xa_erase(), which takes the XArray\nlock without disabling softirqs.\n\nWhen cleanup runs with softirqs enabled, a receive softirq for another\nconnection on the same CPU can interrupt the erase and spin on the lock\nheld by the interrupted task.  Use xa_erase_bh() at both sites to match\nthe insertion path.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/4c9dc0faca98084922caeb689579d338cf3e1c29","tags":[]},{"url":"https://git.kernel.org/stable/c/7110c7f70c59eb7924e79853bcc00e2a026662e6","tags":[]},{"url":"https://git.kernel.org/stable/c/8739f06e3f82cd715f7dd10ab24029ed881efc90","tags":[]},{"url":"https://git.kernel.org/stable/c/bcf97573d44e277b1744d7f1226f665aa0ccc599","tags":[]},{"url":"https://git.kernel.org/stable/c/bea736a2b8c6da5b1078badf1206541b5404250f","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
