CVE-2023-48366
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedRace condition in some Intel(R) System Security Report and System Resources Defense firmware may allow a privileged user to potentially enable information disclosure via local access.
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 confidenceA race condition vulnerability exists in Intel System Security Report and System Resources Defense firmware that allows a privileged user with local access to potentially disclose sensitive information. The race condition occurs during a specific sequence of operations where concurrent access to shared resources is not properly synchronized, leading to a timing window where information can be exposed.

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.
-
Identify Intel System Security Report firmware presenceCheck system firmware inventory or BIOS/UEFI settings for Intel System Security Report component. On Windows, use 'wmic bios get version' or check Intel Driver & Support Assistant. On Linux, check /sys/class/dmi/id/ or use 'dmidecode'. Look for Intel System Security Report in firmware listings.Affected if Intel System Security Report firmware is installed on the system
-
Identify Intel System Resources Defense firmware presenceCheck system firmware inventory for Intel System Resources Defense component. Review BIOS/UEFI firmware version strings or Intel management engine firmware versions. Search for 'System Resources Defense' or 'SRD' in firmware documentation or system reports.Affected if Intel System Resources Defense firmware is installed on the system
-
Determine firmware versions for comparisonRetrieve exact firmware version numbers through Intel tools (Intel System Diagnostic and Discovery or Intel Management Engine Interface), BIOS info dump, or vendor-specific firmware update utilities. Record version strings for comparison against fixed releases.Affected if Firmware version cannot be determined or is earlier than fixed releases available from Intel
-
Verify local privileged access configurationCheck if local administrator or root accounts exist and are accessible. Review user account permissions using 'net user' on Windows or 'cat /etc/passwd' on Linux. Assess whether non-admin users can escalate to privileged access.Affected if Local privileged (administrator/root) accounts are present and accessible to local users
-
Check for concurrent firmware operation logsReview system event logs, Intel firmware logs, or security audit logs for concurrent operations during firmware execution, especially around System Security Report or System Resources Defense features. Look for timing anomalies or access patterns.Affected if Concurrent firmware operations are logged or observable during normal system use
A system is affected if it has Intel System Security Report or System Resources Defense firmware installed and allows local privileged user access, as the race condition requires both the vulnerable firmware components and a privileged local user to trigger the timing window for information disclosure.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the Intel firmware update when available through your system vendor or Intel's support channels. Restrict local access to privileged accounts and monitor for suspicious activity during the window before patching.
