Zephyrproject: >> Zephyr Security Vulnerabilities
In DA, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS09915215; Issue ID: MSV-3801.

When the Global Pointer (GP) relative addressing is enabled (CONFIG_RISCV_GP=y), the gp reg points at 0x800 bytes past the start of the .sdata section which is then used by the linker to relax accesses to global symbols.
