Name of the Vulnerable Software and Affected Versions HUAWEI nova 4 versions earlier than 10.0.0.165(C01E34R2P4) SydneyM-AL00 versions earlier than 10.0.0.165(C00E66R1P5)

Description The issue is related to an out-of-bounds read and write vulnerability. An attacker with specific permissions can craft a malformed packet with a specific parameter and send it to the affected products. Due to insufficient validation of the packet, this may be exploited to cause information leakage or arbitrary code execution.

Recommendations For HUAWEI nova 4 versions earlier than 10.0.0.165(C01E34R2P4), update to version 10.0.0.165(C01E34R2P4) or later. For SydneyM-AL00 versions earlier than 10.0.0.165(C00E66R1P5), update to version 10.0.0.165(C00E66R1P5) or later. As a temporary workaround, consider restricting access to the affected products to minimize the risk of exploitation.
