CVE-2024-35955

  3. CVE-2024-35955
In the Linux kernel, the following vulnerability has been resolved: kprobes: Fix possible use-after-free issue on kprobe registration When unloading a module, its state is changing MODULE_STATE_LIVE -> MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will take a time. `is_module_text_address()` and `__module_text_address()` works with MODULE_STATE_LIVE and MODULE_STATE_GOING. If we use `is_module_text_address()` and `__module_text_address()` separately, there is a chance that the first one is succeeded but the next one is failed because module->state becomes MODULE_STATE_UNFORMED between those operations. In `check_kprobe_address_safe()`, if the second `__module_text_address()` is failed, that is ignored because it expected a kernel_text address. But it may have failed simply because module->state has been changed to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify non-exist module text address (use-after-free). To fix this problem, we should not use separated `is_module_text_address()` and `__module_text_address()`, but use only `__module_text_address()` once and do `try_module_get(module)` which is only available with MODULE_STATE_LIVE.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: kprobes: soluciona un posible problema de use after free en el registro de kprobe Al descargar un módulo, su estado cambia MODULE_STATE_LIVE -> MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Cada cambio llevará un tiempo. `is_module_text_address()` y `__module_text_address()` funcionan con MODULE_STATE_LIVE y MODULE_STATE_GOING. Si usamos `is_module_text_address()` y `__module_text_address()` por separado, existe la posibilidad de que el primero tenga éxito pero el siguiente falle porque module->state se convierte en MODULE_STATE_UNFORMED entre esas operaciones. En `check_kprobe_address_safe()`, si el segundo `__module_text_address()` falla, se ignora porque esperaba una dirección kernel_text. Pero es posible que haya fallado simplemente porque módulo->estado se cambió a MODULE_STATE_UNFORMED. En este caso, arm_kprobe() intentará modificar la dirección de texto del módulo que no existe (use after free). Para solucionar este problema, no debemos usar `is_module_text_address()` y `__module_text_address()` separados, sino usar solo `__module_text_address()` una vez y hacer `try_module_get(module)` que solo está disponible con MODULE_STATE_LIVE.
