Repeated doublings caused the counter to wrap to zero, resulting in a near-zero-length allocation followed by a copy of the existing samples into the undersized buffer.  A remote peer can trigger the expansion by sending a sufficient number of ACKs on an established connection.\n\nA remote attacker who can establish a TCP connection to a system using the RACK stack can trigger an out-of-bounds write of approximately 512 KB in the kernel heap possibly resulting in a kernel panic.","state":0,"publishedAt":"2026-10-15T07:05:02.295+00:00","modifiedAt":"2026-10-15T16:48:11.023+00:00","affected":[{"ecosystem":"Vendor product","name":"FreeBSD","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unknown\",\n                    \"modules\": [\n                        \"tcp\"\n                    ],\n                    \"product\": \"FreeBSD\",\n                    \"vendor\": \"FreeBSD\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"versionType\": \"release\",\n                            \"version\": \"15.1-RELEASE\",\n                            \"lessThan\": \"p5\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://security.freebsd.org/advisories/FreeBSD-SA-26:70.tcp.asc"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-101307","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-101307","identifiers":["CVE-2026-101307"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
