## Overview

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

ALSA: hda: trace PCM open only after assigning a stream

Stream assignment can fail when hardware streams are exhausted.
Move the tracepoint after the NULL check because its payload accesses
the assigned stream tag.

Detected by static analysis and reviewed with AI-assisted source auditing.
