Summary

CVE-2024-25111 is a high-severity Uncontrolled Recursion (CWE-674) vulnerability in Fedoraproject Fedora. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked in the top 0.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

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.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Input validation can reject or constrain data that would otherwise drive unbounded recursive calls.

DoS protection mechanisms limit the resource-exhaustion impact of uncontrolled recursion without eliminating the flaw.

System monitoring can observe anomalous resource consumption that signals runaway recursion after it begins.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent coding errors such as missing recursion limits or termination conditions.

DE.CM-09 partial match
prevents

Runtime monitoring of compute resources can detect excessive consumption caused by uncontrolled recursion.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover and record uncontrolled recursion flaws before deployment.

PR.IR-04 partial match
prevents

Capacity monitoring and resource provisioning can absorb or limit the impact of runaway recursion.

finds

Security testing in development can detect excessive recursion via static analysis or fuzzing.

prevents

Secure development life cycle requires controls that prevent uncontrolled recursion through design and code review.

prevents

Application security requirements can mandate recursion limits or stack-depth checks.

prevents

Secure system architecture principles include resource-management and input-validation rules that limit recursion.

prevents

Secure coding standards directly prohibit or constrain recursive constructs that could exhaust stack or memory.

finds

Capacity management includes monitoring and limits that mitigate resource exhaustion from runaway recursion.
