What is CVE-2025-38200?

A vulnerability exists in the Linux kernel's i40e driver, which can lead to an integer underflow when specific input is processed. This condition allows for MMIO (Memory-Mapped Input/Output) write access to an invalid memory page, potentially compromising system integrity. The issue stems from the handling of related variables, which can be mitigated by altering their data types. Addressing this vulnerability is crucial to ensure robust security in environments relying on the i40e driver.
