Vulnerability Details 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 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.
