Description:
 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.Product: AndroidVersions: Android kernelAndroid ID:
 A-145286050References: Upstream kernel
Ubuntu-Description:
Notes:
 cascardo> This seems to be like that since binder was added to the
  kernel, ie., binder would allow the thread to be freed while its wait
  member was still in the epoll waitqueue.
 cascardo> Description was taken from patch's comment, as it describes
  the specific race condition that makes this different from CVE-2019-2215.
  I added the first sentence which would be a fair description of both
  this CVE and CVE-2019-2215.
