In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
i3c: master: Fix use-after-free of master->this<\/p>\n
sysfs attribute callbacks for the master controller device dereference
\nmaster->this. However, master->this is freed in
\ni3c_master_detach_free_devs() before the master device itself is
\nreleased.<\/p>\n
As a result, sysfs accesses can dereference a freed master->this
\npointer, leading to a use-after-free.<\/p>\n
Keep master->this alive until i3c_masterdev_release(), which is called
\nafter the master device and its sysfs state are being torn down. Do not
\nfree master->this as part of the normal device detach path.<\/p>\n
On the error path in i3c_master_set_info(), reset master->this and
\nbus.cur_master to NULL before freeing the allocated device.<\/p>\n","protected":false},"excerpt":{"rendered":"
