{"schema":"threatline.record/2","record":{"id":"CVE-2026-102555","aliases":[],"summary":"Libsoup: libsoup: heap buffer overflow via uninitialized length in data-uri base64 decoding","details":"A flaw was found in libsoup. The soup_uri_decode_data_uri() function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling g_base64_decode_inplace(). If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the returned GBytes. This can lead to an out-of-bounds read or application crash when processing a crafted data URI.","categories":["Operating systems"],"product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102555","source_modified_at":"2026-10-15T16:43:05.721Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[{"version":"0:3.6.5-3.el10_2.20","lessThan":"*","versionType":"rpm","status":"unaffected"}],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102555","source_modified_at":"2026-10-15T16:43:05.721Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 6","vendor":"Red Hat","versions":[],"defaultStatus":"unknown"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102555","source_modified_at":"2026-10-15T16:43:05.721Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102555","source_modified_at":"2026-10-15T16:43:05.721Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102555","source_modified_at":"2026-10-15T16:43:05.721Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":8.2,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00369,"percentile":0.29593,"score_date":"2026-10-23"},"published_at":"2026-09-29T17:15:14.482Z","modified_at":"2026-10-15T16:43:05.721Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102555","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T16:43:05.721Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102555","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/errata/RHSA-2026:83618","tags":["vendor-advisory","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-102555","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2543224","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-09-29T18:16:58.196973Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-15T16:43:05.721Z","content_hash":"848927cb71f809bd7505071433d5a40229d8470fc679b3f118a497902f6dc891"}}
