CVE-2020-9117

HUAWEI nova 4 versions earlier than 10.0.0.165(C01E34R2P4) and SydneyM-AL00 versions earlier than 10.0.0.165(C00E66R1P5) have an out-of-bounds read and write vulnerability. An attacker with specific permissions crafts malformed packet with specific parameter and sends the packet to the affected products. Due to insufficient validation of packet, which may be exploited to cause the information leakage or arbitrary code execution.
