CVE-2019-5224 : Exploit Details and Defense Strategies

P30 smartphones with versions earlier than ELLE-AL00B 9.1.0.193(C00E190R1P21) are susceptible to an out of bounds read vulnerability. This vulnerability occurs when the system fails to adequately verify a specific length parameter that is transmitted from an application to the kernel. An attacker must deceive the user into installing a malicious application to exploit this vulnerability, potentially leading to an out of bounds read and disclosure of sensitive information.
