CVE-2024-51461Network attack vector

Service interruption via unbounded interrupted-request memory consumption

Published Apr 11, 2025 · Updated Sep 1, 2025

Resource exhaustion in IBM QRadar WinCollect Agent 10.0 through 10.1.13 allows remote attackers to interrupt service via HTTP. The HTTP request-processing path fails to limit memory consumption after an in-progress request is interrupted, allowing memory use to accumulate. IBM's assessment requires user interaction but no privileges; the required interaction is undisclosed, and the impact is limited to availability.
