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 try_module_get() from __find_tracepoint_module_cb() to find_tracepoint() caller, but that introduced a possible UAF because the module can be unloaded before try_module_get(). In this case, the module object should be freed too. Thus, try_module_get() does not only fail but may access to the freed object.

To avoid that, try_module_get() in __find_tracepoint_module_cb() again.
