CVE-2024-11263 — AI Deep Analysis Summary

🚨 **Essence**: A critical security flaw in Zephyr RTOS (v3.7.0 & earlier).…

🛡️ **CWE**: CWE-270 (Privilege Context Switching Error). 🔍 **Flaw**: The vulnerability stems from how the Global Pointer (gp reg) is handled when `CONFIG_RISCV_GP=y` is active.…

📦 **Vendor**: ZephyrProject-RTOS. 📦 **Product**: Zephyr RTOS. 📅 **Affected Versions**: Version 3.7.0 and all previous versions.…

🔓 **Privileges**: High impact (CVSS Score indicates Complete Impact). 💾 **Data**: Can lead to High Confidentiality, Integrity, and Availability loss.…

🔑 **Auth**: Local Access Required (AV:L). 🧩 **Config**: Requires specific compilation flag `CONFIG_RISCV_GP=y`. 🖱️ **UI**: No User Interaction needed. 📊 **Complexity**: Low (AC:L).…

📜 **Public Exploit**: No PoC or public exploit code currently available in the provided data. 🕵️ **Wild Exploitation**: None reported.…

🔍 **Self-Check**: Scan your Zephyr codebase for `CONFIG_RISCV_GP=y`. 📋 **Verify**: Check if your RTOS version is ≤ 3.7.0. 🧪 **Test**: Review linker scripts and .sdata section handling in your build environment.…

🩹 **Patch**: Yes, an official advisory exists (GHSA-jjf3-7x72-pqm9). 🔄 **Fix**: Update to a version later than 3.7.0 where this GP handling issue is resolved.…

🚧 **Workaround**: Disable Global Pointer relative addressing by setting `CONFIG_RISCV_GP=n` in your configuration. 🛑 **Impact**: This may affect performance or code size but mitigates the vulnerability.…

🔥 **Priority**: HIGH. 🚨 **Urgency**: Critical due to CVSS High score (C:H, I:H, A:H). 📅 **Action**: Immediate review and patching recommended for all RISC-V Zephyr deployments using GP relative addressing.…
