      <title>CVE-2024-26800 — tls: fix use-after-free on failed backlog decryption</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2024-26800</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;tls: fix use-after-free on failed backlog decryption&lt;/p&gt;
&lt;p&gt;When the decrypt request goes to the backlog and crypto_aead_decrypt
returns -EBUSY, tls_do_decryption will wait until all async
decryptions have completed. If one of them fails, tls_do_decryption
will return -EBADMSG and tls_decrypt_sg jumps to the error path,
releasing all the pages. But the pages have been passed to the async
callback, and have already been released by tls_decrypt_done.&lt;/p&gt;
&lt;p&gt;The only true async case is when crypto_aead_decrypt returns
 -EINPROGRESS. With -EBUSY, we already waited so we can tell
tls_sw_recvmsg that the data is available for immediate copy, but we
need to notify tls_decrypt_sg (via the new -&amp;gt;async_done flag) that the
memory has already been released.&lt;/p&gt;</description>
