However, the data left for\nthe last pos may be < sizeof(struct sctp_ifwdtsn_skip), and dereference\nit as struct sctp_ifwdtsn_skip may cause coverflow.\n\nThis patch fixes it by checking the pos against \"the end of the chunk -\nsizeof(struct sctp_ifwdtsn_skip)\" in sctp_ifwdtsn_skip, similar to\nsctp_fwdtsn_skip.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-787"],"references":["https://git.kernel.org/stable/c/32832a2caf82663870126c5186cf8f86c8b2a649","https://git.kernel.org/stable/c/4fbd094d4131a10d06a45d64158567052a35b3f4","https://git.kernel.org/stable/c/5c9367ac5a22d71841bcd00130f9146c9b227d57","https://git.kernel.org/stable/c/6109f5b13ce3e3e537db6f18976ec0e9118d1c6f","https://git.kernel.org/stable/c/79b28f42214a3d0d6a8c514db3602260bd5d6cb5"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:10:08.713834912+00:00"},"epss":{"cve":"CVE-2023-53372","score":0.00385,"percentile":0.32564,"date":"2026-10-31"},"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).
