      <title>CVE-2022-50754 — apparmor: fix a memleak in multi_transaction_new()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-50754</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;apparmor: fix a memleak in multi_transaction_new()&lt;/p&gt;
&lt;p&gt;In multi_transaction_new(), the variable t is not freed or passed out
on the failure of copy_from_user(t-&amp;gt;data, buf, size), which could lead
to a memleak.&lt;/p&gt;
&lt;p&gt;Fix this bug by adding a put_multi_transaction(t) in the error path.&lt;/p&gt;</description>
