The kernel calls deny_write_access() to prevent a file already opened for write from being executed and also prevents files being executed from being opened for write. For some reason this does not extend to files being mmap'ed execute. From an IMA perspective, measuring/appraising the integrity of a file being mmap'ed shared execute, without first making sure the file cannot be modified, makes no sense. This patch prevents files, in policy, already mmap'ed shared write, from being mmap'ed execute. Signed-off-by: Mimi Zohar <zohar@linux.ibm.com> |
