CVE-2025-71272

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> most: core: fix resource leak in most_register_interface error paths<br /> <br /> The function most_register_interface() did not correctly release resources<br /> if it failed early (before registering the device). In these cases, it<br /> returned an error code immediately, leaking the memory allocated for the<br /> interface.<br /> <br /> Fix this by initializing the device early via device_initialize() and<br /> calling put_device() on all error paths.<br /> <br /> The most_register_interface() is expected to call put_device() on<br /> error which frees the resources allocated in the caller. The<br /> put_device() either calls release_mdev() or dim2_release(),<br /> depending on the caller.<br /> <br /> Switch to using device_add() instead of device_register() to handle<br /> the split initialization.
