CVE-2026-74696
A flaw was found in the Linux kernel's TCP Fast Open TFO implementation. During SOREUSEPORT listener migration, the system incorrectly accounts for pending TCP Fast Open requests. This can lead to a Denial of Service DoS by allowing an excessive number of Fast Open requests, potentially exhaustin...
