Memory Leak in Linux Kernel's RAID10 Component

CVE-2025-38444

What is CVE-2025-38444?

A memory leak has been identified in the RAID10 component of the Linux kernel. When the functions raid10_read_request or raid10_write_request register a new request with the REQ_NOWAIT flag, allocated memory is not properly freed from the memory pool. This can lead to unreferenced memory allocations that are not released, potentially resulting in degraded system performance over time. It is crucial for users of affected kernel versions to apply the latest patches to mitigate this risk and maintain optimal system functionality.
