Ubuntu.comUB:CVE-2021-47360CVE-2021-47360
In the Linux kernel, the following vulnerability has been resolved: binder:
make sure fd closes complete During BC_FREE_BUFFER processing, the
BINDER_TYPE_FDA object cleanup may close 1 or more fds. The close
operations are completed using the task work mechanism – which means the
thread needs to return to userspace or the file object may never be
dereferenced – which can lead to hung processes. Force the binder thread
back to userspace if an fd is closed during BC_FREE_BUFFER handling.
