+# Red Hat VEX Fixed CVEs with Upstream Fix Commits
+
+One row per CVE that Red Hat has **fixed** in at least one shipped product
+(per Red Hat's CSAF VEX data), joined against CVE.org's `cvelistV5` records
+to resolve the **upstream git commit(s)** that fixed the issue.
+
+Intended use: benchmarking the ability of models and tools to find real
+security issues in code. For each row with a resolved fix commit, the parent
+commit (`<upstream_fix_commit>^`) of `upstream_repo_url` is a known-vulnerable
+code state, and the commit diff is ground truth for the flaw and its fix.
+
+## Fields
+
+| Field | Description |
+|---|---|
+| `cve` | CVE identifier |
+| `title` | Red Hat flaw title (`component: short description`) |
+| `component` | Component name parsed from the title |
+| `severity` | Red Hat aggregate severity (Low / Moderate / Important / Critical) |
+| `cwe_id`, `cwe_name` | CWE assigned by Red Hat |
+| `cvss_v3_score`, `cvss_v3_vector` | Highest CVSS v3 base score across affected products |
+| `description` | Red Hat vulnerability description |
+| `summary` | Red Hat topic/summary line |
+| `statement` | Red Hat statement (context / applicability), when present |
+| `public_date` | Date the issue became public (ISO 8601) |
+| `discovery_date` | Red Hat discovery/report date |
+| `bugzilla_id` | Red Hat Bugzilla identifier |
+| `cisa_kev` | True if referenced in CISA Known Exploited Vulnerabilities catalog |
+| `rh_advisories` | Red Hat advisories (RHSA/RHBA/RHEA) that shipped a fix |
+| `rh_fixed_packages` | Fixed package NEVRAs (capped at 50 per row) |
+| `references` | Reference URLs from the VEX record |
+| `upstream_fix_commit` | Primary upstream fix commit SHA (first resolved) |
+| `upstream_repo_url` | Upstream repository URL for that commit |
+| `upstream_fix_commits` | All resolved commits: `{repo_url, commit, ref_url, source}` |
+| `upstream_affected_versions` | Affected upstream version ranges (from cvelistV5 CNA data) |
+| `upstream_fixed_versions` | Fixed upstream versions (from cvelistV5 CNA data) |
+| `resolution_source` | How the commit was resolved: `redhat_vex` (commit URL present in Red Hat's own references) or `cvelist` (CVE.org record) — `null` if unresolved |
+
+## Construction
+
+1. Downloaded the full Red Hat CSAF VEX archive from
+   `https://security.access.redhat.com/data/csaf/v2/vex/` and kept only CVEs
+   with a non-empty `product_status.fixed`.
+2. Extracted commit URLs (GitHub, GitLab, cgit, gitweb styles) from the VEX
+   references.
+3. Joined against the CVE.org `cvelistV5` bulk dataset for additional commit
+   references (including kernel.org CNA `versionType: git` ranges) and
+   upstream affected/fixed versions.
+
+Rows without a resolvable upstream commit are retained with
+`resolution_source: null` so consumers can apply their own filters.
+
+## Statistics
+
+- 110,635 Red Hat VEX records scanned; **25,428** CVEs with fixed status (one row each)
+- **7,664** rows with at least one resolved upstream fix commit
+  (1,025 resolved from Red Hat's own references, 6,639 from CVE.org)
+- Commit-resolution rate by era: ~15–25% pre-2021, 50–60% for 2022–2025
+  (driven largely by the Linux kernel CNA publishing fix commits)
+- Severity mix: 2,252 Critical / 5,433 Important / 12,932 Moderate / 4,476 Low
+- Top components with commits: Linux kernel (~4,200), OpenSSL, PHP, tcpdump,
+  ghostscript, FreeRDP
+
+## Caveats
+
+- Commit SHAs are taken from published references and are **not** verified
+  against live repositories; some may be branch-specific backports rather
+  than mainline commits, and multi-commit fixes may be incomplete.
+- `upstream_repo_url` is derived from the commit URL and may point at a web
+  UI path (cgit/gitweb) rather than a clean clone URL.
+- Affected/fixed version data comes from CVE.org CNA containers and varies in
+  quality per CNA.
+- A "fixed" status here means Red Hat shipped a fix in at least one product;
+  other products may remain affected or out of support scope.
+- For model benchmarking, filter on `public_date` relative to a model's
+  knowledge cutoff to control for memorization.
