Details

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 rbtree root node must also be protected by the dqopt->dqiosem, otherwise, giving the right timing, shmemreleasedquot() will trigger a warning because it couldn't find a node in the tree, when the real reason was the root node changing before the search starts: Thread 1 Thread 2 - shmemreleasedquot() - shmem{acquire,release}dquot() - fetch ROOT - Fetch ROOT - acquire dqiosem - wait dqiosem - do something, triger a tree rebalance - release dqiosem - acquire dqiosem - start searching for the node, but from the wrong location, missing the node, and triggering a warning.
