in OpenHarmony v4.1.2 and prior versions allow a local attacker cause DOS through use after free.

in OpenHarmony v4.1.2 and prior versions allow a local attacker cause the device is unable to boot up through out-of-bounds write.

in OpenHarmony v4.1.2 and prior versions allow a local attacker cause information leak through out-of-bounds Read.

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.

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.

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.

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

OpenHarmony-v3.1.2 and prior versions had an Multiple path traversal vulnerability in appspawn and nwebspawn services. 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.
