Overview
Affected versions of this package are vulnerable to Privilege Context Switching Error due to the configuration where the gp register points at 0x800 bytes past the start of the .sdata section, which is then used by the linker to relax accesses to global symbols. An attacker can achieve unauthorized access and manipulation of memory.
