What is CVE-2019-2215?

CVE-2019-2215 is a vulnerability identified in the Android operating system, specifically related to the Android Binder, a key component that facilitates communication between apps and the Linux kernel. This vulnerability is classified as a use-after-free flaw, which occurs when a program continues to use a pointer after it has been freed, potentially leading to arbitrary code execution. If successfully exploited, this can result in elevation of privilege, allowing a malicious application to gain access to system-level capabilities without user consent. The implications of this vulnerability are particularly severe as it requires no user interaction for exploitation, but relies on a malicious or compromised application being installed on the device, or on another vulnerability present in network-facing software.

Potential impact of CVE-2019-2215

Unauthorized Access: Exploiting this vulnerability could grant attackers elevated privileges, enabling them to circumvent security restrictions and access sensitive system files and user data without authorization.
System Compromise: By gaining control over the local application environment, attackers can execute arbitrary code at the kernel level, potentially leading to a full system compromise, where they can manipulate or damage device functionality.
Widespread Exploitation: Given that exploitation requires only a malicious application, the risk extends to a broad range of devices running Android, making it a critical target for cybercriminals and increasing the likelihood of mass exploitation across many users.

CISA has reported CVE-2019-2215

CISA provides regional cyber and physical services to support security and resilience across the United States. CISA monitor the most dangerious vulnerabilities and have identifed CVE-2019-2215 as being exploited but is not known by the CISA to be used in ransomware campaigns. This is subject to change at pace

The CISA's recommendation is: Apply updates per vendor instructions.
