Local attackers can create arbitrary directories or escape application sandbox.If chained with other vulnerabilities it would allow an unprivileged process to gain full root privileges.

OpenHarmony-v3.1.2 and prior versions had a DOS vulnerability in distributedhardware_device_manager when joining a network. Network attakcers can send an abonormal packet when joining a network, cause a nullptr reference and device reboot.

Kernel subsystem within OpenHarmony-v3.1.4 and prior versions in kernel_liteos_a has a kernel stack overflow vulnerability when call SysTimerGettime. 4 bytes padding data from kernel stack are copied to user space incorrectly and leaked.

An unprivileged malicious application would be able to gain code execution within any application installed on the device or cause application crash.

OpenHarmony-v3.1.2 and prior versions had a vulnerability that telephony in communication subsystem sends public events with personal data, but the permission is not set. Malicious apps could listen to public events and obtain information such as mobile numbers and SMS data without permissions.

Kernel subsystem within OpenHarmony-v3.1.4 and prior versions in kernel_liteos_a has a kernel stack overflow vulnerability when call SysClockGettime. 4 bytes padding data from kernel stack are copied to user space incorrectly and leaked.

OpenHarmony-v3.1.4 and prior versions had an vulnerability. PIN code is transmitted to the peer device in plain text during cross-device authentication, which reduces the difficulty of man-in-the-middle attacks.

softbus_client_stub in communication subsystem within OpenHarmony-v3.0.5 and prior versions has an authentication bypass vulnerability which allows an "SA relay attack".Local attackers can bypass authentication and attack other SAs with high privilege.

platform_callback_stub in misc subsystem within OpenHarmony-v3.0.5 and prior versions has an authentication bypass vulnerability which allows an "SA relay attack".Local attackers can bypass authentication and attack other SAs with high privilege.

The ArKUI framework subsystem within OpenHarmony-v3.1.5 and prior versions, OpenHarmony-v3.0.7 and prior versions has an Improper Input Validation vulnerability which local attackers can exploit this vulnerability to send malicious data, causing the current application to crash.

The kernel subsystem hmdfs within OpenHarmony-v3.1.5 and prior versions has an arbitrary memory accessing vulnerability which network attackers can launch a remote attack to obtain kernel memory data of the target system.

The kernel subsystem function check_permission_for_set_tokenid within OpenHarmony-v3.1.5 and prior versions has an UAF vulnerability which local attackers can exploit this vulnerability to escalate the privilege to root.

Communication Wi-Fi subsystem within OpenHarmony-v3.1.4 and prior versions, OpenHarmony-v3.0.7 and prior versions has a null pointer reference vulnerability which local attackers can exploit this vulnerability to cause the current application to crash.
