Description
In the Linux kernel, the following vulnerability has been resolved:

btrfs: free iov when btrfs_uring_read_extent() fails

After btrfs_uring_read_extent(), the caller always jumped to out_acct.
That skips kfree(data->iov), which is only correct for -EIOCBQUEUED
where the deferred path owns the iov. On failure, fall through to
out_free instead.
