CVE-2021-21529
Dell System Update (DSU) 1.9 and earlier versions contain a denial of service vulnerability.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
Dell System Update (DSU) 1.9 and earlier versions contain a denial of service vulnerability. A local authenticated malicious user with low privileges may potentially exploit this vulnerability to cause the system to run out of memory by running multiple instances of the vulnerable application.
