Frequently Asked Questions
Who is exposed to this issue?
Systems running one of the listed Ubuntu kernel packages may be affected if the GRGPIO driver is probed. Exploitation requires local access and low privileges.
What is the practical impact of successful exploitation?
The unchecked allocation result can cause a kernel NULL pointer dereference in grgpio_probe. The supplied severity vector indicates an availability impact only, with no stated confidentiality or integrity impact.
Is user interaction or remote network access required?
No user interaction is required. The provided severity vector identifies the attack vector as local, so it does not describe a remotely exploitable network-facing condition.
