What to do
AI-suggested
A fix has been implemented in the Linux kernel to address this issue by modifying the code to avoid recursive locking. Users should apply the official kernel updates that include this fix once available. No other mitigation actions are indicated.
Description
CVE-2024-43098 is a deadlock vulnerability in the Linux kernel's i3c subsystem. The issue arises because i3c_master_register() acquires the i3cbus lock twice, leading to a potential deadlock. The fix involves using i3cdev->desc->info directly instead of calling i3c_device_get_info(), which avoids acquiring the lock twice.
