CVE-2023-28411
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 · uneditedDouble free in some Intel(R) Server Board BMC firmware before version 2.90 may allow a privileged user to 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 analysisThe same block of memory is freed twice, corrupting the allocator's bookkeeping in ways an attacker can shape toward code execution. It usually stems from tangled ownership of a pointer. The fix is clear, single ownership of each allocation and clearing pointers once they are freed.

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.
dbcve · scoped2.90
Firmware version 2.90 or later
- 1. Identify the exact Intel Server System model number from the affected product list (D50tnp1mhcrlc, D50tnp1mhcpac, D50tnp2mhsvac, D50tnp2mhstac, D50tnp1mhcrac, D50tnp2mfalac, M50cyp1ur204, or M50cyp1ur212)
- 2. Check the current BMC firmware version on the affected system using IPMI, BIOS interface, or Intel's deployment tools
- 3. Navigate to the Intel support page and download the BMC firmware update version 2.90 or later for your specific server model
- 4. Apply the firmware update using Intel's recommended process (typically via BMC web interface, Intel System Update Utility, or IPMI firmware update command)
- 5. After updating, verify the BMC firmware has been upgraded to version 2.90 or later and confirm the system is functioning normally
