CVE-2025-38238 is a medium severity vulnerability in the Linux kernel's fnic driver that causes a crash due to double freeing a frame when FDMI requests time out. The issue occurs when both RHBA and RPA FDMI requests time out, leading to reuse of the same frame for ABTS sending and subsequent double free on completion. The fix involves allocating separate frames for RHBA and RPA and adjusting the ABTS logic accordingly.
