Lifecycle Timeline
2DescriptionCVE.org
A security flaw has been discovered in ggml-org whisper.cpp up to 1.8.2. This vulnerability affects the function whisper_model_load of the file ggml/src/ggml.c. The manipulation results in null pointer dereference. Attacking locally is a requirement. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Null pointer dereference in whisper.cpp up to version 1.8.2 allows a local authenticated attacker to crash the application via a crafted input during model loading. The vulnerable code path is the whisper_model_load function within ggml/src/ggml.c, resulting in a limited availability impact (application denial of service) with no confidentiality or integrity consequences. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Local, authenticated access with low privileges is required - the CVSS 4.0 vector confirms AV:L (local attack vector) and PR:L (low privileges required), meaning the attacker must already have a shell or equivalent access on the target host. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The real-world risk of this vulnerability is very low. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local user with standard (low-privilege) account access on a system running whisper.cpp crafts or supplies a malformed model file to the application. When whisper_model_load processes the file, the missing null check causes an immediate null pointer dereference, crashing the whisper.cpp process. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
