      <title>CVE-2026-45948 — ext4: fix memory leak in ext4_ext_shift_extents()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-45948</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;ext4: fix memory leak in ext4_ext_shift_extents()&lt;/p&gt;
&lt;p&gt;In ext4_ext_shift_extents(), if the extent is NULL in the while loop, the
function returns immediately without releasing the path obtained via
ext4_find_extent(), leading to a memory leak.&lt;/p&gt;
&lt;p&gt;Fix this by jumping to the out label to ensure the path is properly
released.&lt;/p&gt;</description>
