Description OSIDB Bzimport 2026-09-17 19:27:56 UTC 
In the Linux kernel, the following vulnerability has been resolved:

arm64: hibernate: Restore DAIF state on error

Sashiko AI has reported that if swsusp_mte_save_tags() for some reason
fails we return from swsusp_arch_suspend() with DAIF being masked -
that is not what we'd expect. Restore the saved DAIF state before
returning from the error path.
