Description OSIDB Bzimport 2026-08-22 15:48:00 UTC 
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.
