CVE-2025-37845

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, trymoduleget() does not only fail but may access to the freed object.

To avoid that, trymoduleget() in _findtracepointmodulecb() again.
