In the Linux kernel, the following vulnerability has been resolved:
tracing: fprobe events: Fix possible UAF on modules
Commit ac91052f0ae5 ("tracing: tprobe-events: Fix leakage of module refcount") moved trymoduleget() from _findtracepointmodulecb() to findtracepoint() caller, but that introduced a possible UAF because the module can be unloaded before trymoduleget(). In this case, the module object should be freed too. Thus, trymodule_get() does not only fail but may access to the freed object.
To avoid that, trymoduleget() in _findtracepointmodulecb() again.
