  3. 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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tracing: fprobe events: Fix possible UAF on modules. La confirmación ac91052f0ae5 ("tracing: tprobe-events: Fix leakage of module refcount") trasladó try_module_get() de __find_tracepoint_module_cb() al llamador de find_tracepoint(), pero esto introdujo un posible UAF porque el módulo puede descargarse antes que try_module_get(). En este caso, el objeto del módulo también debería liberarse. Por lo tanto, try_module_get() no solo falla, sino que puede acceder al objeto liberado. Para evitarlo, vuelva a intentar try_module_get() en __find_tracepoint_module_cb().
