CVE-2026-98962

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.
