Summary

CVE-2019-2215 is a high-severity Use After Free (CWE-416) vulnerability in Huawei P20 Lite Firmware. Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Client Execution (T1203); ranked in the top 1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2019-2215 is a use-after-free vulnerability (CWE-416) located in binder.c that affects the Android operating system. The flaw resides in the Linux kernel component responsible for inter-process communication and carries Android ID A-141720095 along with a CVSS 3.1 base score of 7.8.

An attacker with the ability to run a malicious local application can exploit the issue without user interaction to escalate privileges from the application sandbox directly to the kernel, achieving full read/write control over kernel memory. Exploitation may also be chained through a separate network-facing vulnerability that first obtains local code execution.

Public references include exploit code and vendor advisories such as the Huawei security bulletin, indicating that device manufacturers should apply kernel patches addressing the binder use-after-free condition. No information on in-the-wild exploitation campaigns is supplied in the source data.

Vulnerability Data

A use-after-free in binder.c allows an elevation of privilege from an application to the Linux Kernel. No user interaction is required to exploit this vulnerability, however exploitation does require either the installation of a malicious local application or a separate…
