Key facts

Description

In the Linux kernel, the following vulnerability has been resolved: apparmor: Fix memleak in aa_simple_write_to_buffer() When copy_from_user failed, the memory is freed by kvfree. however the management struct and data blob are allocated independently, so only kvfree(data) cause a memleak issue here. Use aa_put_loaddata(data) to fix this issue.
