Details

In the Linux kernel, the following vulnerability has been resolved:

tracing: kprobe: Fix memory leak in testgenkprobe/kretprobe_cmd()

testgenkprobecmd() only free buf in fail path, hence buf will leak when there is no failure. Move kfree(buf) from fail path to common path to prevent the memleak. The same reason and solution in testgenkretprobecmd().
