Description
A flaw was found in the Linux kernel's Multiple Device (MD) driver, specifically within the RAID10 implementation. This vulnerability allows a local user to trigger a soft lockup, leading to a Denial of Service (DoS). The issue arises because the md/raid10 component lacks a limit on plugged bio (block input/output) requests during write flushing, causing the CPU to become unresponsive under heavy write operations.
