CVE-2024-31158
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 input validation in UEFI firmware in some Intel(R) Server Board S2600BP Family 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 input validation in UEFI firmware on Intel Server Board S2600BP Family allows a privileged local user to escalate privileges. This is a firmware-level vulnerability where insufficient validation of input could be exploited to gain higher-level system privileges beyond those initially granted.

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 the server modelRun 'dmidecode -s system-product-name' or check the physical server label to confirm it is an Intel Server Board S2600BP family memberAffected if The system is not an Intel S2600BP family board, then it is not affected by this specific CVE
-
Check UEFI firmware versionEnter the UEFI BIOS setup (press F2 during boot) and navigate to the 'System Information' or 'BIOS Version' page, or use 'dmidecode -s bios-version' from LinuxAffected if You cannot retrieve a UEFI firmware version from the system
-
Compare firmware version to patched releasesCompare your installed UEFI firmware version to the Intel advisory for CVE-2024-31158 to determine if it is a version that contains the fixAffected if The installed firmware version is older than the version Intel has listed as corrected for this vulnerability
-
Verify local privileged access existsReview user accounts and permissions on the system to confirm whether any non-administrator local accounts with elevated privileges exist (the exploit requires a privileged local user)Affected if The system has local users with elevated privileges who could potentially exploit the input validation flaw
You are affected if you are running an Intel S2600BP family server with a UEFI firmware version older than the version Intel has patched for CVE-2024-31158, and you have local users with elevated privileges on that system.

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 for the S2600BP family once available. Restrict physical and local access to affected servers until the patch is deployed.
