This should prevent that a multiple TT\nrequests are send at the same time to an originator.\n\nBut if allocation of the send buffer failed, this request must be cleaned\nup again. But indicator for such a failure is \"ret == false\". But the\nactual implementation is checking for \"ret == true\".\n\nThe check must be inverted to not loose the information about the TT\nrequest directly after it was attempted to be sent out. This should avoid\npotential request storms.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":[],"references":["https://git.kernel.org/stable/c/067e413eec2e63c2996909ef55214b3a0eda0be7","https://git.kernel.org/stable/c/21c44a6895f41df811d1c91d10eea194dda2b345","https://git.kernel.org/stable/c/27c7d40008231ae4140d35501b60087a9de2d2c3","https://git.kernel.org/stable/c/5e46c76d9a5062212c4c5f642a5549fd9c057f8a","https://git.kernel.org/stable/c/6055695ea40c64a47e00742c12c99b1a33b4daed"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72231","score":0.00677,"percentile":0.52013,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
