Improper buffer restrictions in BIOS firmware for some Intel(R) NUC Boards, Intel(R) NUC 8 Boards, Intel(R) NUC 8 Rugged Boards and Intel(R) NUC 8 Rugged Kits before version CHAPLCEL.0059 may allow a privileged user to potentially enable escalation of privilege via local access.
AnalysisAI
Improper buffer restrictions in BIOS firmware for some Intel(R) NUC Boards, Intel(R) NUC 8 Boards, Intel(R) NUC 8 Rugged Boards and Intel(R) NUC 8 Rugged Kits before version CHAPLCEL.0059 may allow a. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. This Buffer Overflow vulnerability could allow attackers to corrupt memory to execute arbitrary code or crash the application.
Technical ContextAI
This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. Improper buffer restrictions in BIOS firmware for some Intel(R) NUC Boards, Intel(R) NUC 8 Boards, Intel(R) NUC 8 Rugged Boards and Intel(R) NUC 8 Rugged Kits before version CHAPLCEL.0059 may allow a privileged user to potentially enable escalation of privilege via local access. Affected products include: Intel Nuc 8 Rugged Kit Nuc8Cchkrn Firmware, Intel Nuc 8 Rugged Kit Nuc8Cchkr Firmware, Intel Nuc 8 Rugged Board Nuc8Cchbn Firmware, Intel Nuc Board Nuc8Cchb Firmware.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Use memory-safe languages or bounds-checking. Enable ASLR, DEP/NX, stack canaries. Use safe string functions.
