CVE-2025-71300 Details
Description
In the Linux kernel, the following vulnerability has been resolved: Revert "arm64: zynqmp: Add an OP-TEE node to the device tree" This reverts commit 06d22ed6b6635b17551f386b50bb5aaff9b75fbe. OP-TEE logic in U-Boot automatically injects a reserved-memory node along with optee firmware node to kernel device tree. The injection logic is dependent on that there is no manually defined optee node. Having the node in zynqmp.dtsi effectively breaks OP-TEE's insertion of the reserved-memory node, causing memory access violations during runtime.
A vulnerability has been identified in the Linux kernel's handling of the OP-TEE node within the device tree for Zynq UltraScale+ MPSoC. This issue arises because the OP-TEE logic in U-Boot relies on the absence of a manually defined OP-TEE node to properly inject a reserved-memory node into the kernel device tree. The presence of the node in 'zynqmp.dtsi' disrupts this injection, leading to memory access violations during runtime. This vulnerability affects several versions of the Linux kernel.
The vulnerability has been addressed by reverting the addition of the OP-TEE node in the 'zynqmp.dtsi' file. Users can apply the latest patches from the Linux kernel stable tree to mitigate this issue.
