  "description": "In the Linux kernel, the following vulnerability has been resolved:  btrfs: fix race between quota enable and quota rescan ioctl  When enabling quotas, at btrfs_quota_enable(), after committing the transaction, we change fs_info-\u003Equota_root to point to the quota root we created and set BTRFS_FS_QUOTA_ENABLED at fs_info-\u003Eflags. Then we try to start the qgroup rescan worker, first by initializing it with a call to qgroup_rescan_init() - however if that fails we end up freeing the quota root but we leave fs_info-\u003Equota_root still pointing to it, this can later result in a use-after-free somewhere else.  We have previously set the flags BTRFS_FS_QUOTA_ENABLED and BTRFS_QGROUP_STATUS_FLAG_ON, so we can only fail with -EINPROGRESS at btrfs_quota_enable(), which is possible if someone already called the quota rescan ioctl, and therefore started the rescan worker.  So fix this by ignoring an -EINPROGRESS and asserting we can\u0027t get any other error.",
