Summary

CVE-2024-12886 is a high-severity Data Amplification (CWE-409) vulnerability. Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

This vulnerability is AI-related — categorised as NLP and Transformers; in the Data-Related Vulnerabilities risk domain.

The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) and SC-5 (Denial-of-service Protection) — see the control section below for these in your framework.

Vulnerability Data

An Out-Of-Memory (OOM) vulnerability exists in the `ollama` server version 0.3.14. This vulnerability can be triggered when a malicious API server responds with a gzip bomb HTTP response, leading to the `ollama` server crashing. The vulnerability is present in the…

more

`makeRequestWithRetry` and `getAuthorizationToken` functions, which use `io.ReadAll` to read the response body. This can result in excessive memory usage and a Denial of Service (DoS) condition.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation can reject or limit decompression of data whose expansion ratio exceeds safe thresholds.

SC-5 Denial-of-service Protection partial match

DoS protection limits the resource-exhaustion impact when a decompression bomb is processed.

SC-6 Resource Availability partial match

Resource allocation controls bound memory/CPU consumption that a data-amplification attack would otherwise exhaust.

DE.CM-09 partial match
blocks

Runtime monitoring of compute resources can detect exhaustion caused by decompression bombs.

PR.IR-04 partial match
blocks

Capacity planning and monitoring directly limits the availability impact of data-amplification attacks.

PR.PS-06 partial match
blocks

Secure-development practices include input-validation and resource-limit checks that prevent improper handling of compressed data.
