The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N","score":6.8},"cwes":["CWE-310","CWE-200"],"references":["http://www.securityfocus.com/bid/99338","http://www.securitytracker.com/id/1038915","https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-7526","https://eprint.iacr.org/2017/627","https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git%3Ba=commit%3Bh=78130828e9a140a9de4dafadbc844dbb64cb709a"],"products":["canonical:ubuntu_linux","debian:debian_linux","gnupg:libgcrypt"],"source":"nvd","synced_at":"2026-10-19T20:52:03.425131697+00:00"},"epss":{"cve":"CVE-2017-7526","score":0.03835,"percentile":0.90106,"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).
