You can do this with ptrace or with /proc/pid/mem without a kernel
patch.
To make this safe would need a ptrace_may_acces(PTRACE_MODE_READ)

Adds /proc//text_md5sum which, when read, calculates an md5sum over
the process' text segment. This can detect some cases where the system RAM
has been disturbed by e.g. ESD or cosmic radiation (on systems where ECC
is not available). It might also detect some accidental or malicious
modifications
Adds /proc/pid/text_md5sum which, when read, calculates an md5sum over
the process' text segment. This can detect some cases where the system RAM
has been disturbed by e.g. ESD or cosmic radiation (on systems where ECC
is not available). It might also detect some accidental or malicious
