Malformed base64 image data sent to the /api/chat endpoint makes mtmd_helper_bitmap_init_from_buf return NULL, which is dereferenced without a check, causing a segmentation fault that crashes the runner process. A remote attacker can cause a denial of service, leaving the model unavailable to all users until the service is restarted.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-15514","publishedAt":"2026-01-13T04:15:51.957Z","cveId":"CVE-2025-15514","cweIds":["CWE-395"],"cvssScore":"7.5","cvssSeverity":"high","severity":"high","attackType":["denial_of_service"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Ollama"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Ollama null pointer dereference in multi-modal image processing via /api/chat","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00765,"epssCheckedAt":"2026-11-04T12:08:35.257Z","kevDateAdded":null,"advisoryAliases":["GHSA-6q56-mrmc-cph4"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-04T00:12:45.455Z","patchAvailable":null,"disclosureDate":null,"fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["availability"],"aiComponentTargeted":"inference","llmSpecific":true,"classifierConfidence":0.93,"researchCategory":null,"atlasIds":null,"fixes":[]}}
