Similarly, ncsi_rcv_rsp() exits early\nwhen failing to resolve the NCSI device, response handler, or\nrequest, leaving the skb unfreed.","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":["CWE-401"],"references":["https://git.kernel.org/stable/c/553366c271479c0d571dd1bb5d1bcde4747fb82e","https://git.kernel.org/stable/c/59962588197863d0d746879f193905c0c6b3df49","https://git.kernel.org/stable/c/5c3398a54266541610c8d0a7082e654e9ff3e259","https://git.kernel.org/stable/c/81d6aee32f8f7bbc175c05dbf61f4430bfb88c4a","https://git.kernel.org/stable/c/87138dde2d6937b12b967f28fe598a7d59000ae4"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43373","score":0.00501,"percentile":0.42936,"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).
