  3. CVE-2025-21679
In the Linux kernel, the following vulnerability has been resolved: btrfs: add the missing error handling inside get_canonical_dev_path Inside function get_canonical_dev_path(), we call d_path() to get the final device path. But d_path() can return error, and in that case the next strscpy() call will trigger an invalid memory access. Add back the missing error handling for d_path().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: btrfs: agregar la gestión de errores faltante dentro de get_canonical_dev_path Dentro de la función get_canonical_dev_path(), llamamos a d_path() para obtener la ruta final del dispositivo. Pero d_path() puede devolver un error y, en ese caso, la siguiente llamada a strscpy() activará un acceso a memoria no válido. Agregue nuevamente la gestión de errores faltante para d_path().
