CVE-2026-45888

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> md/raid1: fix memory leak in raid1_run()<br /> <br /> raid1_run() calls setup_conf() which registers a thread via<br /> md_register_thread(). If raid1_set_limits() fails, the previously<br /> registered thread is not unregistered, resulting in a memory leak<br /> of the md_thread structure and the thread resource itself.<br /> <br /> Add md_unregister_thread() to the error path to properly cleanup<br /> the thread, which aligns with the error handling logic of other paths<br /> in this function.<br /> <br /> Compile tested only. Issue found using a prototype static analysis tool<br /> and code review.
