If an attacker can trigger the allocation of these limited resources, but the number or size of the resources is not controlled, then the attacker could cause a denial of service that consumes all available resources. This would prevent valid users from accessing the product, and it could potentially have an impact on the surrounding environment. For example, a memory exhaustion attack against an application could slow down the application as well as its host operating system.\nThere are at least three distinct scenarios which can commonly lead to resource exhaustion:\nResource exhaustion problems are often result due to an incorrect implementation of the following situations:","Draft","Class","Simple",{"shortDescription":73,"requiredAction":73,"vulnerabilityName":73,"dateAdded":27},"",[],{"title":76,"metaDescription":77,"keywords":78,"canonicalUrl":79,"structuredData":80},"What is CVE-2026-45498?
