      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring/rw: end write accounting from ->ki_complete\n\nCommit b000145e9907 moved both the fsnotify calls and the write\naccounting out of the kiocb completion handler and into the\nio_req_rw_complete() task_work. However, only the fsnotify part actually\nneeded to move as it may sleep. Ending the write accounting is just a\npercpu_up_read() on the superblock writers sem.\n\nDeferring it is a problem, because it makes dropping SB_FREEZE_WRITE\nprotection depend on the ring owner getting to running task_work.
