CVE-2022-49891

In the Linux kernel, the following vulnerability has been resolved: tracing: kprobe: Fix memory leak in testgenkprobe/kretprobecmd testgenkprobecmd only free buf in fail path, hence buf will leak when there is no failure. Move kfreebuf from fail path to common path to prevent the memleak. The sam...
