This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted computed hmac sum to an untrusted input sum if an attacker can send a zeroed buffer in place of a pre-computed sum.  It is also possible to force a derived key to be all zeros instead of an unpredictable value.  This may have follow-on implications for the Go TLS stack.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:L","score":6.5},"cwes":["CWE-457"],"references":["https://access.redhat.com/errata/RHSA-2024:10133","https://access.redhat.com/errata/RHSA-2024:7502","https://access.redhat.com/errata/RHSA-2024:7550","https://access.redhat.com/errata/RHSA-2024:8327","https://access.redhat.com/errata/RHSA-2024:8678"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2024-9355","score":0.00298,"percentile":0.22234,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3h3x-2hwv-hr52","url":"https://osv.dev/vulnerability/GHSA-3h3x-2hwv-hr52","summary":"Golang FIPS OpenSSL has a Use of Uninitialized Variable vulnerability","modified":"2026-09-21T18:45:04.700597509Z","packages":[{"ecosystem":"Go","name":"github.com/golang-fips/openssl","purl":"pkg:golang/github.com/golang-fips/openssl","ranges":["<=2.0.3"],"fixed":[]}]},{"id":"GO-2024-3167","url":"https://osv.dev/vulnerability/GO-2024-3167","summary":"Golang FIPS OpenSSL has a Use of Uninitialized Variable vulnerability in github.com/golang-fips/openssl","modified":"2026-03-03T04:55:50.086919Z","packages":[{"ecosystem":"Go","name":"github.com/golang-fips/openssl","purl":"pkg:golang/github.com/golang-fips/openssl","ranges":["all versions"],"fixed":[]}]}],"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).
