Race Condition Vulnerability in Linux Kernel Affecting Buffer Write Operations

CVE-2025-38429

What is CVE-2025-38429?

A race condition vulnerability in the Linux kernel exists in the mhi_ep_ring_add_element function, where the read pointer is updated before the buffer is fully written. This premature update can allow the host to interact with an uninitialized or incomplete element, leading to potential data corruption and unintended behavior. To mitigate this issue, it is essential to invoke the buffer write operation before updating the read pointer. This ensures that the element is entirely written before it is made available for access.
