CVE-2026-8108 is a vulnerability in Fuji Electric Tellus version 5.0.2 where a kernel driver is installed with overly permissive read and write access for all users. This condition corresponds to CWE-749, indicating exposure of a dangerous method or function that can be abused by local users with limited privileges. The vulnerability has a CVSS 3.1 base score of 7.8, reflecting high impact on confidentiality, integrity, and availability. No official patch or remediation level has been provided by the vendor, and no exploits are currently known in the wild.

The vulnerability allows local users with limited privileges to read from and write to a kernel driver, potentially leading to full system compromise including confidentiality, integrity, and availability impacts. Because the kernel driver is accessible with read/write permissions by all users, an attacker could leverage this to execute arbitrary code or disrupt system operations.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict local user access to the affected system and monitor for suspicious activity. Avoid running untrusted code or users with local access on affected versions. Follow vendor communications for updates on patches or mitigations.
