CVE-2025-38200
In the Linux kernel, the following vulnerability has been resolved: i40e: fix MMIO write access to an invalid page in i40e_clear_hw When the device sends a specific input, an integer underflow can occur, leading to MMIO write access to an invalid page.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
