  "description": "In the Linux kernel, the following vulnerability has been resolved:  tmpfs: fix race on handling dquot rbtree  A syzkaller reproducer found a race while attempting to remove dquot information from the rb tree.  Fetching the rb_tree root node must also be protected by the dqopt-\u003Edqio_sem, otherwise, giving the right timing, shmem_release_dquot() will trigger a warning because it couldn\u0027t find a node in the tree, when the real reason was the root node changing before the search starts:  Thread 1\t\t\t\tThread 2 - shmem_release_dquot()\t\t\t- shmem_{acquire,release}_dquot()  - fetch ROOT\t\t\t\t- Fetch ROOT  \t\t\t\t\t- acquire dqio_sem - wait dqio_sem  \t\t\t\t\t- do something, triger a tree rebalance \t\t\t\t\t- release dqio_sem  - acquire dqio_sem - start searching for the node, but   from the wrong location, missing   the node, and triggering a warning.",
