CVE-2021-22487

Service availability impact via out-of-bounds read

Published Oct 28, 2021 · Updated Aug 3, 2024

Out-of-bounds read in MindSpore EMUI 11.0.0 allows attackers to affect service availability via crafted device input. The Huawei bulletin does not disclose the component or exact input-processing locus, only that an out-of-bounds read exists in some Huawei phones. Exploitation therefore requires access to an affected phone and can disrupt service availability; confidentiality and integrity effects are not reported.
