In the Linux kernel, the following vulnerability has been resolved:
ima: Instantiate file_truncate and path_truncate hooks
Instantiate the file_truncate and path_truncate LSM hooks to reset the
action cache flags (IMA_DONE_MASK) as soon as truncation is requested,
so the file, based on policy, is re-collected, re-measured, re-audited,
and re-appraised on next access.
