What is CVE-2019-5226?
Certain Huawei smartphones, including the P30, P30 Pro, and Mate 20, as well as the HiSuite software, are susceptible to a version downgrade vulnerability. This occurs due to insufficient validation of upgrade packages, allowing the system of the smartphone to be reverted to an earlier, possibly less secure version. Devices running specific software versions are particularly at risk, as they do not adequately check the integrity of the upgrade path, potentially exposing users to older vulnerabilities that may have been patched in subsequent releases.
