CVE-2024-11263— arch: riscv: userspace: potential security risk when CONFIG_RISCV_GP=y

Quick assessment

Affected
zephyrproject-rtos Zephyr
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Zephyr是Zephyr开源的一个可扩展的实时操作系统 (RTOS)。 Zephyr 3.7.0版本及之前版本存在安全漏洞，该漏洞源于当启用全局指针 (GP) 相对寻址 (CONFIG_RISCV_GP=y) 时，gp reg 指向 .sdata 部分开始处的 0x800 字节，然后链接器使用该字节来放宽对全局符号的访问。
