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 · high confidenceDell SupportAssist OS Recovery versions prior to 5.5.15.1 create temporary files with insecure permissions, allowing a low-privileged local attacker to potentially read or modify these files, leading to information tampering.

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.
-
Verify Dell SupportAssist OS Recovery is installedLook for Dell SupportAssist OS Recovery in the list of installed programs via Add/Remove Programs, or check for its installation directory in Program FilesAffected if The software is present on the system
-
Identify the installed version of Dell SupportAssist OS RecoveryOpen the Windows Registry under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\SupportAssistOS or check the application's About/Properties window for the version numberAffected if The version displayed cannot be determined or is shown as an older release
-
Compare your version against the affected rangeNote the full version number found and compare it numerically to 5.5.15.1Affected if The installed version is lower than 5.5.15.1 (for example, 5.5.10.0, 5.4.0.0, etc.)
-
Confirm the application runs with elevated privilegesCheck if Dell SupportAssist OS Recovery executes with administrator or SYSTEM privileges by viewing its process properties in Task ManagerAffected if The process runs with elevated privileges while creating world-readable/writable temp files
You are affected if Dell SupportAssist OS Recovery is installed and its version is below 5.5.15.1, as earlier versions create temporary files with overly permissive access controls exploitable by local users.
