Agree. They are looking for an "attack" This is DOS for sure. More discussions here. https://www.examtopics.com/discussions/comptia/view/41268-exam-cs0-002-topic-1-question-8-discussion/

Whilst DOS is a reasonable guess here, Memory Corruption is the answer. In this scenario DOS will be a symptom rather than the cause - https://owasp.org/www-community/vulnerabilities/Memory_leak

Not sure if you read the full article here... It actually says Most memory leaks result in general software reliability problems, but if an attacker can intentionally trigger a memory leak, the attacker might be able to launch a denial of service attack (by crashing the program) or take advantage of other unexpected program behavior resulting from a low memory condition [1]. So to me then the answer should be C and not B

Selected Answer: B
I should go for B. Denial of service attack usually works in the network resources unless it is the other type of DOS attack which is the exploitation of vulnerabilities. But we are talking about memory here, memory exploitation will definitely make the system crash. A DOS attack usually makes the system unavailable to the users but doesn't mean that it is down, It's just inaccessible because of the overwhelming packets. In the "root cause analysis revealed a bad actor forced the application to not reclaim memory", this is caused by memory manipulation and exploitation, so it is B for sure
