      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnilfs2: fix potential UAF of struct nilfs_sc_info in nilfs_segctor_thread()\n\nThe finalization of nilfs_segctor_thread() can race with\nnilfs_segctor_kill_thread() which terminates that thread, potentially\ncausing a use-after-free BUG as KASAN detected.\n\nAt the end of nilfs_segctor_thread(), it assigns NULL to \"sc_task\" member\nof \"struct nilfs_sc_info\" to indicate the thread has finished, and then\nnotifies nilfs_segctor_kill_thread() of this using waitqueue\n\"sc_wait_task\" on the struct nilfs_sc_info.\n\nHowever, here, immediately after the NULL assignment to \"sc_task\", it is\npossible that nilfs_segctor_kill_thread() will detect it and return to\ncontinue the deallocation, freeing the nilfs_sc_info structure before the\nthread does the notification.\n\nThis fixes the issue by protecting the NULL assignment to \"sc_task\" and\nits notification, with spinlock \"sc_state_lock\" of the struct\nnilfs_sc_info.  Since nilfs_segctor_kill_thread() does a final check to\nsee if \"sc_task\" is NULL with \"sc_state_lock\" locked, this can eliminate\nthe race.",
