CVE-2026-98018
What it is
In the Linux kernel, the following vulnerability has been resolved: net: mctp: i3c: serialize probe with bus removal mctp_i3c_probe() drops busdevs_lock after finding the matching bus. A concurrent I3C_NOTIFY_BUS_REMOVE can then unregister and free the bus netdev before probe passes its private data to mctp_i3c_add_device(). The latter consequently adds a list node through a freed mbus pointer. Keep busdevs_lock held until the device has been added. This also satisfies the __must_hold annotation on mctp_i3c_add_device().
