CVE-2024-43098: i3c: Use i3cdev->desc->info instead of calling i3c_device_get_info() to avoid deadlock

Published Jan 11, 2025

Updated

In the Linux kernel, the following vulnerability has been resolved:

i3c: Use i3cdev->desc->info instead of calling i3cdevicegetinfo() to avoid deadlock

A deadlock may happen since the i3cmasterregister() acquires &i3cbus->lock twice. See the log below. Use i3cdev->desc->info instead of calling i3cdeviceinfo() to avoid acquiring the lock twice.

v2: - Modified the title and commit message

============================================ WARNING: possible recursive locking detected 6.11.0-mainline -------------------------------------------- init/1 is trying to acquire lock: f1ffff80a6a40dc0 (&i3cbus->lock){++++}-{3:3}, at: i3cbusnormaluselock

but task is already holding lock: f1ffff80a6a40dc0 (&i3cbus->lock){++++}-{3:3}, at: i3cmasterregister

other info that might help us debug this: Possible unsafe locking scenario:

CPU0 ---- lock(&i3cbus->lock); lock(&i3cbus->lock);

DEADLOCK

May be due to missing lock nesting notation

2 locks held by init/1: #0: fcffff809b6798f8 (&dev->mutex){....}-{3:3}, at: driverattach #1: f1ffff80a6a40dc0 (&i3cbus->lock){++++}-{3:3}, at: i3cmasterregister
