CVE-2023-26299
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 · uneditedA potential Time-of-Check to Time-of-Use (TOCTOU) vulnerability has been identified in certain HP PC products using AMI UEFI Firmware (system BIOS), which might allow arbitrary code execution. AMI has released updates to mitigate the potential vulnerability.
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.

- Identify the specific HP product model from the affected list (260 G4 Desktop Mini, T430, T628, 240 G10, 245 G6, 245 G7, 245 G8, or 247 G8)
- Navigate to HP Support at support.hp.com and enter the product model number to access its support page
- Locate the BIOS/Firmware section and download the latest firmware version matching or exceeding: 260 G4 Desktop Mini: 2.14, T430: 00.01.11, T628: 00.01.10, 240 G10: f.04, 245 G6: f.35, 245 G7: f.69, 245 G8: f.25, 247 G8: f.69

- Allow the firmware update to complete without interruption; the system will restart automatically
- Verify the updated firmware version matches the target version after reboot
