Huawei HarmonyOS buffer overflow vulnerability

Huawei HarmonyOS is an operating system from Huawei, a Chinese company that provides a microkernel-based distributed operating system. A buffer overflow vulnerability exists in Huawei HarmonyOS, which stems from the failure of the kernel server to perform length checksum on user-state passed data. An attacker could exploit the vulnerability to cause a kernel-side read out-of-bounds to occur, affecting device confidentiality and availability.
