CVE-2023-49618
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 · uneditedImproper buffer restrictions in some Intel(R) System Security Report and System Resources Defense firmware may allow a privileged user to potentially enable escalation of privilege 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 confidenceImproper buffer restrictions in Intel System Security Report and System Resources Defense firmware may allow a privileged local user to exploit buffer handling weaknesses and escalate privileges beyond their current access level.

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 if Intel System Security Report firmware is presentCheck system firmware/inventory for Intel System Security Report component. On Windows, use 'wmic bios get version' or check Intel Management Engine firmware version. On Linux, check /sys/class/dmi/id/ or use 'dmidecode'. Look for Intel-related firmware entries indicating System Security Report functionality.Affected if The Intel System Security Report firmware component is found on the system
-
Identify if Intel System Resources Defense firmware is presentSimilar to above, search for Intel System Resources Defense in firmware listings, BIOS/UEFI information, or Intel management engine components. Check Intel firmware update utilities if available.Affected if The Intel System Resources Defense firmware component is found on the system
-
Determine firmware version of affected componentsRetrieve the specific firmware version number for the Intel System Security Report and System Resources Defense components using Intel firmware update tools, BIOS information, or system inventory reports. Note the exact version string.Affected if A specific firmware version is returned that can be compared against fixed versions
-
Verify privilege context requirementConfirm that the system allows local privileged user accounts. Check for accounts with administrative or elevated privileges that could potentially exploit this vulnerability.Affected if Local privileged user accounts exist on the system and the vulnerable firmware components are present
The system is affected if Intel System Security Report or System Resources Defense firmware is installed and the installed version is lower than the version that includes the security fix for CVE-2023-49618.
