Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Revert "arm64: zynqmp: Add an OP-TEE node to the device tree"<br /> <br /> This reverts commit 06d22ed6b6635b17551f386b50bb5aaff9b75fbe.<br /> <br /> OP-TEE logic in U-Boot automatically injects a reserved-memory<br /> node along with optee firmware node to kernel device tree.<br /> The injection logic is dependent on that there is no manually<br /> defined optee node. Having the node in zynqmp.dtsi effectively<br /> breaks OP-TEE&amp;#39;s insertion of the reserved-memory node, causing<br /> memory access violations during runtime.
