Authenticated service interruption via firmware over-read
Published Feb 10, 2026 · Updated Feb 10, 2026
Out-of-bounds read in Intel E810 firmware before cvl fw 1.7.6 and cpk 1.3.7 allows remote authenticated users to interrupt service. Intel identifies the firmware boundary error but does not disclose the affected parser, message type, or exact read that crosses its buffer. The path requires network access, low-privilege credentials, and attack-specific internal knowledge; exploitation interrupts adapter availability without reported data disclosure or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
