A stack-based buffer overflow vulnerability exists in the PGP verification component due to incorrect length handling when copying EdDSA 's' MPI into a stack buffer. A remote attacker could craft a malicious Ed25519 PGP signature with mismatched MPI lengths. Processing this crafted signature could lead to a denial of service in automated package or repository processing workflows.","published_at":"2026-07-16T00:46:12.846000Z","last_modified_at":"2026-08-24T13:19:04.023000Z","cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":true,"ssvc_technical_impact":"partial","cwes":["CWE-121"],"nvd_references":["https://access.redhat.com/security/cve/CVE-2026-48863","https://bugzilla.redhat.com/show_bug.cgi?id=2460975","https://github.com/openSUSE/libsolv/commit/44f8c085045b1f771641091bbb2b810d12cff9e8#diff-309f245ec9b669ec78b8159c39e6f50130b4d4a0448f742685f7833d04bc4caaR592"],"vuln_status":"Awaiting Analysis","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-07-16T01:35:28.548204Z","updated_at":"2026-08-24T19:35:50.286612Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"opensuse","vendor_name":"openSUSE","product_slug":"libsolv","product_name":"libsolv","version_start":"0.6.4","version_start_inclusive":true,"version_end":"0.7.38","version_end_inclusive":false,"cpe23_uri":"cve5:opensuse:libsolv:0.6.4:0.7.38"}],"exploit_refs":[],"news":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-48863","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2460975","source_type":"MISC","tags":[]},{"url":"https://github.com/openSUSE/libsolv/commit/44f8c085045b1f771641091bbb2b810d12cff9e8#diff-309f245ec9b669ec78b8159c39e6f50130b4d4a0448f742685f7833d04bc4caaR592","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-07-16T00:46:12.846000Z","label":"CVE published","source":null},{"type":"ssvc_changed","at":"2026-07-18T03:36:28.554444Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-07-18T03:36:28.554444Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-07-18T03:36:28.554444Z","label":"SSVC decision revised","source":"vulnrichment"}]}
