CWE-283  (opens in a new tab)

How to fix?

Upgrade camelot-os/sentry-kernel to version 0.4.7 or higher.

Overview

Affected versions of this package are vulnerable to Unverified Ownership via the __sys_int_* syscall family. An attacker can disrupt system availability or establish covert channels by manipulating another task's IRQ line if they possess DEV or IO capabilities. This is only exploitable if multiple tasks are assigned DEV or IO capabilities.

Workaround

This vulnerability can be mitigated by reducing tasks that have the DEV and IO capability to a single one.
