CVE-2021-39686

Published: 16 March 2022

In several functions of binder.c, there is a possible way to represent the wrong domain to SELinux due to a race condition. 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-200688826References: Upstream kernel

Notes

AuthorNote
sbeattie
AppArmor is the default MAC LSM for Ubuntu, not SELinux,
though it is possible to boot with SELinux enforcement in place.
