      <title>CVE-2024-50272 — filemap: Fix bounds checking in filemap_read()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-50272</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;filemap: Fix bounds checking in filemap_read()&lt;/p&gt;
&lt;p&gt;If the caller supplies an iocb-&amp;gt;ki_pos value that is close to the
filesystem upper limit, and an iterator with a count that causes us to
overflow that limit, then filemap_read() enters an infinite loop.&lt;/p&gt;
&lt;p&gt;This behaviour was discovered when testing xfstests generic/525 with the
&amp;#34;localio&amp;#34; optimisation for loopback NFS mounts.&lt;/p&gt;</description>
