Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceImproper input validation in Zoom Desktop Client for Linux before version 5.15.10 allows an unauthenticated attacker to cause a denial of service via network access. The vulnerability stems from the client failing to properly validate incoming network data, which can be exploited remotely without authentication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Zoom client version via command lineRun `zoom --version` or `zoom -v` in a terminal to display the installed Zoom Desktop Client for Linux version numberAffected if The displayed version number is less than 5.15.10 (for example, 5.14.0, 5.15.5, etc.)
-
Check Zoom package version via package managerRun `dpkg -l | grep zoom` for Debian-based systems or `rpm -qa | grep zoom` for RPM-based systems to list the installed Zoom package and its versionAffected if The version listed is lower than 5.15.10
-
Verify Zoom is running and accessible via networkConfirm the Zoom client is installed and running on a Linux system, as the vulnerability is exploitable via network access to the clientAffected if Zoom Desktop Client for Linux is installed and running, and the version is below 5.15.10
The environment is affected if the installed Zoom Desktop Client for Linux version is any version lower than 5.15.10.
