We all known barriers are paired (see memory-barriers.txt: &#34;Note that write barriers should normally be paired with read or address-dependency barriers&#34;), therefore accessing it from concurrent contexts requires read barrier. Previous commit added such barrier in qcom_scm_is_available(), so let&#39;s use that directly.</p> <p>Lack of this read barrier can result in fetching stale &#39;__scm&#39; variable value, NULL, and dereferencing it.</p> <p>Note that barrier in qcom_scm_is_available() satisfies here the control dependency.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>firmware: qcom: scm: Fix missing read barrier in qcom_scm_get_tzmem_pool()</p> <p>Commit 2e4955167ec5 (&#34;firmware: qcom: scm: Fix __scm and waitq completion variable initialization&#34;) introduced a write barrier in probe function to store global &#39;__scm&#39; variable.
