      <title>CVE-2024-26684 — net: stmmac: xgmac: fix handling of DPP safety error for DMA channels</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-26684</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;net: stmmac: xgmac: fix handling of DPP safety error for DMA channels&lt;/p&gt;
&lt;p&gt;Commit 56e58d6c8a56 (&amp;#34;net: stmmac: Implement Safety Features in
XGMAC core&amp;#34;) checks and reports safety errors, but leaves the
Data Path Parity Errors for each channel in DMA unhandled at all, lead to
a storm of interrupt.
Fix it by checking and clearing the DMA_DPP_Interrupt_Status register.&lt;/p&gt;</description>
