CVE-2026-45952

A flaw was found in the Linux kernel's fbnic driver. This vulnerability allows a local user to cause a Denial of Service DoS by increasing the Maximum Transmission Unit MTU beyond the hardware's threshold while an eXpress Data Path XDP program is attached. This improper validation of MTU changes...
