Summary
In the Linux kernel, the following vulnerability has been resolved:
iio: trigger: sysfs: fix possible memory leak in iio_sysfs_trig_init()
dev_set_name() allocates memory for name, it need be freed
when device_add() fails, call put_device() to give up the
reference that hold in device_initialize(), so that it can
be freed in kobject_cleanup() when the refcount hit to 0.
Fault injection test can trigger this:
unreferenced object 0xffff8e8340a7b4c0 (size 32):
comm "modprobe", pid 243, jiffies 4294678145 (age 48.845s)
hex dump (first 32 bytes):
