Unnecessary goto: When the first DMA mapping (sfc->daddr) fails,\n   nothing needs cleanup. Use direct return instead of goto.\n2. Double-unmap bug: When info DMA mapping failed, the code would\n   unmap sfc->daddr inline, then fall through to out_map_data which\n   would unmap it again, causing a double-unmap.\n3. Wrong unmap size: The out_map_info label used datalen instead of\n   infolen when unmapping sfc->iaddr, which could lead to incorrect\n   DMA sync behavior.","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":[],"references":["https://git.kernel.org/stable/c/0a83d6c9e149a176340190fa9cbadf2266db4c9a","https://git.kernel.org/stable/c/b20b437666e1cb26a7c499d1664e8f2a0ac67000","https://git.kernel.org/stable/c/c0b88f1176074f80140ed77fce909f254b7180ab"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43461","score":0.00119,"percentile":0.01744,"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).
