The kernel subsystem function checkpermissionforsettokenid 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.

The bundle management subsystem within OpenHarmony-v3.1.4 and prior versions has a null pointer reference vulnerability which local attackers can exploit this vulnerability to cause a DoS attack to the system when installing a malicious HAP package.

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.

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.

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.

The appspawn and nwebspawn services within OpenHarmony-v3.1.2 and prior versions were found to be vulnerable to buffer overflow vulnerability due to insufficient input validation. 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 have an incorrect configuration of the cJSON library, which leads a Stack overflow vulnerability during recursive parsing. LAN attackers can lead a DoS attack to all network devices.

OpenHarmony-v3.1.2 and prior versions have a heap overflow vulnerability. Local attackers can trigger a heap overflow and get network sensitive information.

OpenHarmony-v3.1.2 and prior versions have a permission bypass vulnerability. Local attackers can bypass permission control and get sensitive information.
