- Summary
- CVE-2026-93200 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
i3c: master: Fix use-after-free of master->this
sysfs attribute callbacks for the master controller device dereference master->this. However, master->this is freed in i3c_master_detach_free_devs() before the master device itself is released.
As a result, sysfs accesses can dereference a freed master->this pointer, leading to a use-after-free.
Keep master->this alive until i3c_masterdev_release(), which is called after the master device and its sysfs state are being torn down. Do not free master->this as part of the normal device detach path.
On the error path in i3c_master_set_info(), reset master->this and bus.cur_master to NULL before freeing the allocated device.
