CVE-2025-38200 Details
Description
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. Prevent the integer underflow by changing the type of related variables.
A vulnerability in the Linux kernel's i40e network driver has been identified, where certain input from the device can cause an integer underflow. This underflow allows for Memory-Mapped Input/Output (MMIO) write access to an invalid memory page. The issue has been addressed by modifying the variable types involved to prevent the underflow.
