However, this chunk is leaked in several code\npaths:\n\n1. In sctp_sf_do_5_1B_init(), if security_sctp_assoc_request() fails after\n   sctp_verify_init() has populated err_chunk, the function returns\n   immediately without freeing it.\n\n2. In sctp_sf_do_unexpected_init(), the same leak occurs on the\n   security_sctp_assoc_request() failure path.\n\n3. In sctp_sf_do_unexpected_init(), on the success path after copying\n   unrecognized parameters to the INIT-ACK, the function returns without\n   freeing err_chunk, unlike sctp_sf_do_5_1B_init() which properly frees\n   it.\n\nFix all three leaks by adding sctp_chunk_free(err_chunk) calls before\nreturning in the error paths and on the success path in\nsctp_sf_do_unexpected_init().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1cae40d423a2042c7970f29c00028951ec20db8a","https://git.kernel.org/stable/c/43ddbcdc0ed74a8fba4aff5e623ace8135411b93","https://git.kernel.org/stable/c/6acedac7a14af71cfe25024ead28e16a070899e4","https://git.kernel.org/stable/c/94f55994e19e8f0676990b9d5015b58ab6a97e00","https://git.kernel.org/stable/c/9f58a0a4d6c2ed5d341bba64f058f15d1b0c36f2"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72413","score":0.00211,"percentile":0.11304,"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).
