Name of the Vulnerable Software and Affected Versions: Prague smart phones versions earlier than Prague-AL00AC00B211 Prague smart phones versions earlier than Prague-AL00BC00B211 Prague smart phones versions earlier than Prague-AL00CC00B211 Prague smart phones versions earlier than Prague-TL00AC01B211 Prague smart phones versions earlier than Prague-TL10AC01B211 Description: The Bdat driver has an integer overflow issue due to a lack of parameter validation. This can be exploited by an attacker who tricks a user into installing a malicious APP, which can then send a specific parameter to the driver, potentially leading to arbitrary code execution. Recommendations: For versions earlier than Prague-AL00AC00B211, update to Prague-AL00AC00B211 or later. For versions earlier than Prague-AL00BC00B211, update to Prague-AL00BC00B211 or later. For versions earlier than Prague-AL00CC00B211, update to Prague-AL00CC00B211 or later. For versions earlier than Prague-TL00AC01B211, update to Prague-TL00AC01B211 or later. For versions earlier than Prague-TL10AC01B211, update to Prague-TL10AC01B211 or later.

Name of the Vulnerable Software and Affected Versions: Huawei smartphones with software of MHA-AL00AC00B125 Description: The issue is related to improper resource management in the software. Specifically, the software does not properly manage resources during device register operations. An attacker could exploit this by tricking a user with root privilege into installing a crafted application, which could lead to certain services becoming unavailable. Recommendations: For Huawei smartphones with software of MHA-AL00AC00B125, at the moment, there is no information about a newer version that contains a fix for this vulnerability.

Name of the Vulnerable Software and Affected Versions: Huawei smartphones version MHA-AL00AC00B125 Description: The issue is related to an integer overflow that occurs when the software improperly handles a certain variable during a specific process. An attacker could exploit this by tricking a user with root privileges into installing a crafted application, potentially leading to information disclosure. Recommendations: For version MHA-AL00AC00B125, at the moment, there is no information about a newer version that contains a fix for this vulnerability.

**Name of the Vulnerable Software and Affected Versions** Huawei mobile phones with software earlier than MHA-AL00BC00B231 **Description** The issue is related to a lack of parameter validation, which can lead to a denial-of-service (DOS) condition. An attacker could potentially trick a user into installing a malicious application (APP) that modifies specific parameters to cause the system to reboot. **Recommendations** For versions earlier than MHA-AL00BC00B231, consider restricting the installation of applications from untrusted sources to minimize the risk of exploitation. As a temporary workaround, avoid using applications that request modification of system parameters until a patch is available.
