--- title: "CVE-2019-2214\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2019-2214?format=md keywords: index, follow --- # CVE-2019-2214 Publication date 13 November 2019 Last updated 4 July 2026 --- Ubuntu priority **Medium** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) ## Cvss 3 Severity Score **7.8 · High** [Score breakdown](https://ubuntu.com/security/CVE-2019-2214?format=md#impact-score) Toggle side navigation ## Description In binder\_transaction of binder.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-136210786References: Upstream kernel ### From the Ubuntu Security Team It was discovered that the binder IPC implementation in the Linux kernel did not properly perform bounds checking in some situations, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- |
