CVE-2024-43098
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
i3c: Use i3cdev->desc->info instead of calling i3c_device_get_info() to avoid deadlock
A deadlock may happen since the i3c_master_register() acquires &i3cbus->lock twice. See the log below. Use i3cdev->desc->info instead of calling i3c_device_info() to avoid acquiring the lock twice.
============================================ WARNING: possible recursive locking detected 6.11.0-mainline -------------------------------------------- init/1 is trying to acquire lock: f1ffff80a6a40dc0 (&i3cbus->lock){++++}-{3:3}, at: i3c_bus_normaluse_lock
