CVE-2019-5296
Description
Mate20 Huawei smartphones versions earlier than HMA-AL00C00B175 have an out-of-bounds read vulnerability. An attacker with a high permission runs some specific commands on the smartphone. Due to insufficient input verification, successful exploit may cause out-of-bounds read of the memory and the system abnormal.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A high-privilege attacker can trigger an out-of-bounds memory read on Mate20 smartphones, causing system instability.
Vulnerability
An out-of-bounds read vulnerability exists in Huawei Mate20 smartphones running versions earlier than HMA-AL00C00B175. The flaw resides in insufficient input verification during the execution of specific commands with high permissions, allowing a local attacker to cause a read beyond the bounds of allocated memory [1].
Exploitation
An attacker must obtain high system permissions on the device (kernel or root-level access) and then run crafted commands that trigger the out-of-bounds read condition. No user interaction is required beyond the initial privilege escalation, and the attack is conducted locally on the device [1].
Impact
Successful exploitation results in out-of-bounds memory read, which may cause the system to become unstable or crash. The vulnerability does not provide code execution or data exfiltration on its own, but the resulting denial-of-service condition can affect device availability [1].
Mitigation
Huawei released a software update to address this vulnerability. The fix is included in version HMA-AL00C00B175 and later for the Mate20. Users should update their devices to the latest firmware [1].
