Out-of-bounds write in firmware for some Intel(R) NUCs may allow an authenticated user to potentially enable denial of service via local access.
AnalysisAI
Out-of-bounds write in firmware for some Intel(R) NUCs may allow an authenticated user to potentially enable denial of service via local access. Rated medium severity (CVSS 5.5), 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 firmware for some Intel(R) NUCs may allow an authenticated user to potentially enable denial of service via local access. Affected products include: Intel Nuc M15 Laptop Kit Lapbc510 Firmware, Intel Nuc M15 Laptop Kit Lapbc710 Firmware, Intel Nuc 11 Compute Element Cm11Ebc4W Firmware, Intel Nuc 11 Compute Element Cm11Ebi38W Firmware, Intel Nuc 11 Compute Element Cm11Ebi58W Firmware.
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).
