      <title>CVE-2026-23193 — scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-23193</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;scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count()&lt;/p&gt;
&lt;p&gt;In iscsit_dec_session_usage_count(), the function calls complete() while
holding the sess-&amp;gt;session_usage_lock. Similar to the connection usage count
logic, the waiter signaled by complete() (e.g., in the session release
path) may wake up and free the iscsit_session structure immediately.&lt;/p&gt;
&lt;p&gt;This creates a race condition where the current thread may attempt to
execute spin_unlock_bh() on a session structure that has already been
deallocated, resulting in a KASAN slab-use-after-free.&lt;/p&gt;
&lt;p&gt;To resolve this, release the session_usage_lock before calling complete()
to ensure all dereferences of the sess pointer are finished before the
waiter is allowed to proceed with deallocation.&lt;/p&gt;</description>
