Catalin Visinescu a30bbfee6b drivers/: Multiple Drivers Are Registered With World Writable Part 3
Summary

Permissions (Part 3)

Description:

In kernel builds, any unprivileged process running on the NuttX device can
open /dev/efuse and attempt to read/write fuse content. Reading the fuses
may provide valuable information to an attacker controlling the user process.
The write operation, in extreme cases where the fuse blocks are not locked,
may brick the device.

DISCLAIMER: I tried to be strict with the settings, better to relax them
later if it's needed.
