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. The Linux kernel CVE team has assigned CVE-2025-71300 to this issue. Affected and fixed versions =========================== Issue introduced in 6.9 with commit 06d22ed6b6635b17551f386b50bb5aaff9b75fbe and fixed in 6.12.75 with commit eece81eeda10eb42c687399fb5aa69977ae15664 Issue introduced in 6.9 with commit 06d22ed6b6635b17551f386b50bb5aaff9b75fbe and fixed in 6.18.16 with commit 3983ef126e439900bbf419724a9759863c146660 Issue introduced in 6.9 with commit 06d22ed6b6635b17551f386b50bb5aaff9b75fbe and fixed in 6.19.6 with commit 2a833c730d4e8d1cc10953270ce0f3a156145d81 Issue introduced in 6.9 with commit 06d22ed6b6635b17551f386b50bb5aaff9b75fbe and fixed in 7.0 with commit c197179990124f991fca220d97fac56779a02c6d Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2025-71300 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: arch/arm64/boot/dts/xilinx/zynqmp.dtsi Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/eece81eeda10eb42c687399fb5aa69977ae15664 https://git.kernel.org/stable/c/3983ef126e439900bbf419724a9759863c146660 https://git.kernel.org/stable/c/2a833c730d4e8d1cc10953270ce0f3a156145d81 https://git.kernel.org/stable/c/c197179990124f991fca220d97fac56779a02c6d
