      <title>CVE-2023-53607 — ALSA: ymfpci: Fix BUG_ON in probe function</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2023-53607</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;ALSA: ymfpci: Fix BUG_ON in probe function&lt;/p&gt;
&lt;p&gt;The snd_dma_buffer.bytes field now contains the aligned size, which this
snd_BUG_ON() did not account for, resulting in the following:&lt;/p&gt;
