DescriptionNVD

Out-of-bounds write in the firmware for Intel(R) Ethernet 700 Series Controllers before version 8.2 may allow a privileged user to potentially enable an escalation of privilege via local access.

AnalysisAI

Out-of-bounds write in the firmware for Intel(R) Ethernet 700 Series Controllers before version 8.2 may allow a privileged user to potentially enable an escalation of privilege via local access. Rated medium severity (CVSS 6.7), this vulnerability is low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. Out-of-bounds write in the firmware for Intel(R) Ethernet 700 Series Controllers before version 8.2 may allow a privileged user to potentially enable an escalation of privilege via local access. Affected products include: Intel Ethernet Controller V710-At2 Firmware, Intel Ethernet Controller X710-Tm4 Firmware, Intel Ethernet Controller X710-At2 Firmware, Intel Ethernet Controller Xxv710-Am2 Firmware, Intel Ethernet Controller Xxv710-Am1 Firmware. Version information: version 8.2.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
