AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
An out-of-bounds read/write in Huawei Mate 30 due to insufficient input validation allows a local attacker to cause denial of service via modified configuration.
Vulnerability
CVE-2020-9211 is an out-of-bounds read and write vulnerability in the Huawei Mate 30 smartphone running EMUI 10.1.0.126(C00E125R5P3). A system module does not sufficiently verify input. Attackers can modify certain configuration to trigger out-of-bounds access [1].
Exploitation
Exploitation requires the attacker to have local access to the device and the ability to modify configuration. The precise sequence of steps is not disclosed, but the advisory indicates that modifying configuration leads to the out-of-bounds condition [1].
Impact
Successful exploitation causes out-of-bounds read and write operations, resulting in a denial of service (DoS) [1]. There is no indication of data confidentiality or integrity compromise.
Mitigation
Huawei released a fix in EMUI 11.0.0.145(C00E145R7P11). Users should update to this or a later version to remediate the vulnerability [1]. No workaround is mentioned.
