"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: f_tcm: fix deadlock in usbg_make_tpg()\n\nusbg_make_tpg() held dep_lock while calling\nconfigfs_depend_item_unlocked(), which acquires the configfs root\ninode lock when operating across subsystems. This creates a circular\nlock dependency with configfs_rmdir():\n\n dep_lock -> configfs root inode lock -> su_mutex -> dep_lock\n\nIn usbg_make_tpg(), dep_lock only serialized the read of opts->ready,\nwhich is a monotonic flag that transitions from false to true exactly\nonce (in tcm_set_name()) and never reverts. Remove dep_lock from\nusbg_make_tpg() entirely and use READ_ONCE/WRITE_ONCE to access\nopts->ready locklessly instead."
