  "description": "In the Linux kernel, the following vulnerability has been resolved:  btrfs: unlock inode and extent in caller when io_uring read extent fails  btrfs_uring_read_extent() runs only after btrfs_encoded_read() has taken the inode shared lock and the extent lock.  On failure it used to unlock in out_fail, and a pages-array allocation failure returned -ENOMEM without unlocking at all.  Unlock in the caller instead on all failure returns, matching the copy_to_user() error path.  The deferred -EIOCBQUEUED path still unlocks in btrfs_uring_read_finished().",
