Description msiddiqu 2020-04-30 13:12:51 UTC 
A vulnerability was found in the Linux kernel. In binder_thread_release of binder.c, there is a possible use after free 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.
