Technical description
In the Linux kernel, the following vulnerability has been resolved:
liveupdate: fix TOCTOU race in luo_session_retrieve()

overlap with the acquisition of the session mutex. This prevents a
concurrent thread from releasing and freeing the session between the
lookup and the mutex lock.
