Attackers can craft malicious binaries containing strings or constant byte stores that end in multi-byte lead units to trigger out-of-bounds reads that crash the decompiler or leak adjacent heap memory into decompiled output.","categories":["Unclassified"],"product":"ghidra","vendor":"NationalSecurityAgency","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100505","source_modified_at":"2026-10-05T14:55:05.029Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"ghidra","vendor":"NationalSecurityAgency","versions":[{"version":"9.2","lessThanOrEqual":"12.1.4","status":"affected","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":4.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00143,"percentile":0.03323,"score_date":"2026-10-23"},"published_at":"2026-09-26T00:36:33.247Z","modified_at":"2026-10-05T14:55:05.029Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100505","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T14:55:05.029Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100505","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/NationalSecurityAgency/ghidra/commit/e37c57f3d9c29511a1860f0a735df53131d403d7","tags":["patch"]},{"source":"CVE List","url":"https://github.com/NationalSecurityAgency/ghidra","tags":["product"]},{"source":"CVE List","url":"https://github.com/NationalSecurityAgency/ghidra/blob/8b6bbb857accdfa20dc5b2f5dea471178c2e9fbc/Ghidra/Features/Decompiler/src/decompile/cpp/stringmanage.cc#L324-L410","tags":["technical-description"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/ghidra-11.2-through-12.1.4-heap-out-of-bounds-read-via-stringmanager","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-05T14:01:09.982721Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-05T14:55:05.029Z","content_hash":"2f3e910396f94b49f6d3a60783649bbab32113645db4994a305ae83d26f9336e"}}
