An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-15514 exists.\n\nAffected product: Ollama. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-15514/ (Markdown: https://insights.sbomify.com/CVE-2025-15514/index.md)","id":"CVE-2025-15514","markdown":"https://insights.sbomify.com/CVE-2025-15514/index.md","name":"CVE-2025-15514","record":{"aliases":["GHSA-6q56-mrmc-cph4","MINI-wg3g-7j27-5v6x"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"LLM inference server","requires_auth":"none","summary":"Remote attackers can crash the Ollama service by sending malformed base64 image data, causing a denial of service for all users.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"ollama","vendor":"ollama"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-395","name":"Use of NullPointerException Catch to Detect NULL Pointer Dereference"}],"description":"Ollama 0.11.5-rc0 through current version 0.13.5 contain a null pointer dereference vulnerability in the multi-modal model image processing functionality. When processing base64-encoded image data via the /api/chat endpoint, the application fails to validate that the decoded data represents valid media before passing it to the mtmd_helper_bitmap_init_from_buf function. This function can return NULL for malformed input, but the code does not check this return value before dereferencing the pointer in subsequent operations. A remote attacker can exploit this by sending specially crafted base64 image data that decodes to invalid media, causing a segmentation fault and crashing the runner process. This results in a denial of service condition where the model becomes unavailable to all users until the service is restarted.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Ollama Multi-Modal Model Image Processing NULL Pointer Dereference","id":"CVE-2025-15514","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2025"},"n_packages":0,"n_references":4,"next":{"headline":"Auth bypass in Easyshare","id":"CVE-2025-15515"},"packages":[],"prev":{"headline":"Float Payment Gateway \u003c= 1.1.9 - Improper Authorization to Unauthenticated Order Status Manipulation","id":"CVE-2025-15513"},"products":["Ollama"],"published":"2026-01-12","related":[{"cvss_score":9.8,"headline":"Ollama Platform has missing authentication enabling attackers to perform model management operations","id":"CVE-2025-63389","kev_date_added":null,"published":"2025-12-18"},{"cvss_score":9.1,"headline":"Ollama can extract members of a ZIP archive outside of the parent directory","id":"CVE-2024-45436","kev_date_added":null,"published":"2024-08-29"},{"cvss_score":8.8,"headline":"Ollama heap out-of-bounds read in GGUF tensor parsing leaks server process memory to unauthenticated remote attackers","id":"CVE-2026-7482","kev_date_added":null,"published":"2026-05-04"},{"cvss_score":8.8,"headline":"Ollama does not validate the format of the digest (sha256 with 64 hex digits)","id":"CVE-2024-37032","kev_date_added":null,"published":"2024-05-31"},{"cvss_score":8.2,"headline":"Ollama Out-of-bounds Read","id":"CVE-2024-39720","kev_date_added":null,"published":"2024-10-31"},{"cvss_score":7.7,"headline":"Missing Signature Verification for Updates in Ollama","id":"CVE-2026-42248","kev_date_added":null,"published":"2026-04-29"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-16","vendors":["Ollama"]},"summary":"Remote attackers can crash the Ollama service by sending malformed base64 image data, causing a denial of service for all users.","url":"https://insights.sbomify.com/CVE-2025-15514/"}
